Juicy J knows how to party, but not every waking moment in the electric rapper's life is a turnt-up twerk-a-thon. Take, for instance, the time Juice worked with Katy Perry on an upcoming song from her Prism album.

"I just did something with Katy Perry, man. That song is amazing," Juicy said of the track, which will be released early on September 17 after a fan-voted contest.

Though we haven't heard Juice's verse yet — we've only heard a snippet of the track — a determined Katy appears to have her sights set on a certain lover, and she won't take no for an answer. "So you wanna play with magic/ Boy, you should know whatcha fallin' for," she sings in a breathy tone.

"Dr. Luke called me up and was like, 'Hey man, Katy Perry wants you to do a song with her'," J said of the "Roar" producer.

Juice says that the recording session with Perry went smooth, so when "RapFix Live" host Sway Calloway inquired as to whether or not there was any twerking in between vocal takes, the rapper was very clear in his response.

"No, no, no, no. She's very professional, everything went smooth and she's a great person," he said. "My verse I did on that song, she was singing it. She's really a genius, she was by the mixing board and telling the guy what to take in and take out. She's really hands-on with her music, she knows music."

Though he's been in the industry for over 20 years, Juice is having a resurgence ...

You would think, given the seemingly unending conversation surrounding her VMA performance, Miley Cyrus would be fine to spend Labor Day weekend lying low.

But you'd be wrong ... after all, like the lyrics to her recent hit suggest, she can't stop -- and she won't stop.

Check out the promo images for Bangerz here!

She took little time to rest after Sunday night, getting right back to work making a cameo in Mike Will Made It's "23" video, which came on the heels of releasing the second single off her Bangerz album, the intense ballad

So on Thursday, we got our first glimpse at promotional pics for Miley's album, and while they're nowhere near as talked about as her twerk-tastic Video Music Awards performance, they should be enough to keep the conversation going through the long weekend.

Take, for example, one image, where Miley, clad in checkered leather pants and a cropped top, defiantly grabs her crotch. In another — which recalls the Bangerz album cover — she's photographed with her back to the camera, a black dress barely covering her backside.

There are, of course, more demure images too: Miley clutching a bouquet of flowers, Miley holding balloons and striking a confident pose, a pensive portrait where she momentarily shows us her soft side ... but based on early coverage, it seems (not surprisingly), that folks are focusing on the more salacious photos.

It's been a while since we last saw an installment in Vin Diesel's other franchise on the big screen, but all that changes when "Riddick" opens in theaters on September 6.

In the film, Diesel reprises the role he originated in 2000's "Pitch Black." It's the first appearance of the fearless mercenary Riddick since his appearance in the decidedly more epic "Chronicles of Riddick" from 2004. But nine years away from theaters is a long time; Diesel's made three "Fast and the Furious" films starring his character Dom Toretto in that gap. What kept the ferocious Furyan out of theaters for so long?

"The trick was to service both the audience from 'Pitch Black' and the audience from 'Chronicles of Riddick,' and do that all while maintaining a rated-R feel," Diesel revealed to MTV at San Diego Comic-Con. "And as you know, when you're doing the really, really big budget movies, it's difficult to get a studio to sign off on a rated-R movie. And yet, they did — or they finally did."

"Finally" is definitely the key word there. The modestly budgeted and R-rated "Pitch Black" was a surprise hit when it was released, finding a cult audience that craved more of the antiheroes antics, but the big-budget follow-up "Chronicles of Riddick" came up short at the box office. Diesel hypothesized that that may be due to the difference in the R-rated original and the less successful sequel's softer PG-13 rating.

"['Riddick'] is an intense film," explained Diesel. "Being a rated-R film sets it apart from the other stuff that you see, so ...

Lately, Lady Gaga has been getting her rocks off.

Earlier this week, she posted rehearsal footage of a new ARTPOP track called which features a driving, industrial groove, some classic-rock inspired guitars and, of course, Gaga smashing and bashing away on a stripped-down drum kit. Needless to say, it rocked way harder than anything else in her arsenal.

But now, she's released another rehearsal clip — she's set to perform at London's iconic Roundhouse on Sunday as part of iTunes Music Festival (her performance will also be streamed live to fans around the world) — this one for a song called "Manicure," and, with its booming, bad-ass backbeat and crunching chords, it rocks pretty hard too (it also sounds a lot like Joan Jett's "Bad Reputation" ... or Grace Potter's "Paris," for that matter).

And based on the rehearsal footage, Gaga is channeling their swagger too. First, her dancers strap a pair of towering, sparkly heels on her feet, and then, as her band kicks in behind her, LG struts and pouts, thrusts her first in the air, and clutches the mic like she's trying to choke the life out of it. To be honest, we're not entirely sure what she's singing ... though that's precisely the point, as Gaga took to Twitter to let fans know the sound quality of the rehearsal clips "has been obstructed to give you a taste of ARTPOP but ultimately confuse you until Sunday."

Consider us confused then. Of course, Gaga also tweeted the lyrics to "Manicure," which with lines like "You're the medicine I ...

Put your hands up! Lady Gaga's November 11 album release, ARTPOP is getting closer and closer to its release. And this weekend she's slated to preview tracks during the iTunes Festival.

Before she takes the stage on September 1, she's already teased the track in addition to dropping the latest single (which she also performed at the VMAs last Sunday).

Ahead of Gaga's performance at the iTunes Fest, MTV News spoke to ARTPOP producer, DJ White Shadow, who revealed what it's been like to work on this release, her follow-up to 2011's Born This Way.

"We didn't make 15 trees; we made a forest. She's writing every single song, so they're coming from her," he said, sharing, "It was less than a week that she had hit me [after Born This Way]... and she literally sent me [the note] 'The next album's called ARTPOP.' She had the name and the general concept for the record a week after Born This Way came out."

In the two years-plus since that album's release, Gaga has been through a lot, including having to cancel her Born This Way tour to recover from hip surgery. And if fans are wondering how Gaga has grown on this next album release, White Shadow explained, "It's just another step on the ladder, it's another step forward. It's different, it's a different record. We didn't sit down and say 'ARTPOP has to be this.' It's like that's how she's feeling at the time. I think it's a really fun album. There's really fun stuff on ...

"Saving Mr. Banks" tells the tale of how Walt Disney (Tom Hanks) courted original "Mary Poppins" author P.L. Travers (Emma Thompson) for the film rights to her beloved children's book, eventually turning it into the classic 1964 film. With the film set in the ultra-fashionable 1960s, actor B.J. Novak made sure that his time spent on the "Saving Mr. Banks" set was well-documented.

"I loved the ['Saving Mr. Banks'] wardrobe," Novak revealed to MTV News during our recent Fall Movie Preview interview. "['The Office' wardrobe] was anything you could buy at Sears. On 'Saving Mr. Banks' even the socks are like 1962 vintage socks. The hair is all crusted over. I loved it. I'm not one to take selfies, but I broke my rule for this project because it was so fun and cool to play dress up like that. I turned into a 16-year-old girl."

Novak plays Robert Sherman, one half of the legendary songwriting duo the Sherman brothers, who were responsible for penning the film's memorable tunes. Novak is best known for his seven years as a writer and actor on the hit NBC sitcom, "The Office," a show that featured a slightly different aesthetic from "Saving Mr. Banks."

In addition to the upgraded wardrobe, Novak got to work alongside multiple Academy Award-winner Tom Hanks, whose living-legend status made him the perfect choice to play Walt Disney. "It feels like movie history in and of itself," said Novak of Hanks' casting as the imaginative innovator. "He's perfect casting. Walt Disney was sort of an all-American optimist, a symbol of upbeat ...

One Direction made history when Up All Night debuted at #1 last year. Now, the first British group to have their first album debut at the top of the Billboard charts has their sights set on #1 somewhere else: the box office.

Fresh off their Best Song of the Summer win for "Best Song Ever" at last weekend's Video Music Awards, the boys from 1D have debuted "One Direction: This is Us" in North American theaters. The film blends backstage moments and concert footage, captured by "Supersize Me!" documentary filmmaker Morgan Spurlock and produced by Simon Cowell, who put 1D together.

Sixty-eight percent of Fandango's ticket sales were for "This Is Us" on Thursday, with 98 percent of those going to females. Industry analysts are predicting a four-day weekend in the neighborhood of $22 million for the 3-D flick, less than the $31.1 million three-day opening for Miley Cyrus' 2008 3-D concert movie, "Best of Both Worlds." It should also trail behind concert films from the late Michael Jackson and 2011's "Justin Bieber: Never Say Never."

However that $22 million (ish) should be enough to swipe the #1 spot, unless two-time champion "Lee Daniels' The Butler" edges out Niall, Zayn, Liam, Louis and Harry. The historical drama debuted at #1 and held onto the top spot during its second weekend, fending off the likes of horror flick "You're Next" and franchise wannabe "The Mortal Instruments: City of Bones."

If "The Butler" had the $15.1 million four-day weekend projected by BoxOfficeMojo.com and the Los Angeles Times, it should be smooth sailing for ...

Two weeks after their secret wedding
 in Pennsylvania, Amber Rose and Wiz Khalifa finally shared some details of their blessed day on Thursday during their first post-nuptials interview.

"It was better than I thought it was gonna be," Amber told Hot 97's Angie Martinez about the blessed day. "It was beautiful. I'm so proud of my baby for what she did," added Wiz. "She put all of that together and everybody's ranting and raving over every little detail about it. Those things didn't happen on their own, she did it."

And yeah, Khalifa cried during the ceremony, while Amber said she cried walking down the aisle, during the ceremony and at the reception. For now, there's no honeymoon because Khalifa is working on his next album. In fact, he said he was in the studio the day after the wedding working on tracks. "Thank you for letting me work," he said to Rose. "I'm working on my album, Blacc Hollywood."

With love clearly in full bloom ("I don't think you understand how much I love this man" Amber gushed), the pair also talked about their good friend, Miley Cyrus, and her now legendary performance at the VMAs. Though she was secretive about the details, Amber also revealed that she's now being managed by Miley's mom, Tish and is working on a non-musical project with her best friend, Priscilla Ono.

"Young, wild and free," Wiz said in describing Cyrus' twerk-tastic VMA moment. "You gotta let people do what they wanna do." Amber said the couple love Cyrus, ...

A day at the beach for Beyoncé is not like a day at the beach for the rest of us. When Mrs. Carter rolls up at Coney Island in Brooklyn, sure, she rides the Cyclone while wearing a Biggie hat and a bunch of gold chains. And sure she gets the front car every time, but that's because she's mixing business with pleasure and filming a new music video.

According to reports, the singer spent the day at the seaside amusement part on Thursday enjoying some down time with stylist Ty Hunter and some of her dancers, while shooting footage for a video for an unnamed song for her upcoming, as-yet-unscheduled album.

Check out photos of Bey riding Coney Island's Cyclone coaster!

Wearing jeans, a white tank with a black bra underneath and the B.I.G. snapback, Bey spent nearly an hour on the ride with a couple dozen extras, according to E! News. Several hundred people gathered to watch the shoot and get a glimpse of the star as she laughed and threw her hands in the air on the 86-year-old coaster. The New York Daily News reported that famed fashion photographer Terry Richardson was directing the clip.

A spokesperson for Beyoncé could not be reached for comment at press time about the shoot or where the footage will be used.

This isn't the first time this month that Queen B has gotten her amusement park on. Two weeks ago while on a break from playing at the V Festival Beyoncé hit the coasters in England.

The two stars of "Ender's Game," Gavin Hood's upcoming adaptation of the beloved book, have something unique in common. Both Asa Butterfield and Hailee Steinfeld are two young actors, who are just now following up their breakout roles in films by revered directors — Martin Scorse's "Hugo" and the Coen brothers' "True Grit," respectively.

When MTV News' spoke with them at San Diego Comic-Con, the two actors explained what it's like to follow up their first big films with something like "Ender's Game," which is a part of our Fall Movie Preview.

"For me, there isn't much that could follow up 'Hugo,' " Butterfield said to MTV News' Josh Horowitz, "but 'Ender's Game' does it."

Steinfeld had a surprisingly similar experience with "Ender's Game" as she had had with "True Grit," since her characters in both films were highly sought-after parts. "I think it has a lot to do with everyone involved loving the story," she said. "For me, 'Ender's Game' came along in sort of the same way that 'True Grit' did. You feel fortunate that something that great has come your way. You fall in love with it. I'm so proud to be a part of it."

The pressure of "Ender's Game" came not only from adapting a beloved book, but acting across from a movie legend, Harrison Ford. Butterfield said that, of course, he was nervous, but in the end, it was a rewarding experience. "I think everyone was nervous," he said. "When I first got to work with him, it was near the start of shooting. I was, as ...
