Lady Gaga is the definition of dangerous glamour in Robert Rodriguez's playing with guns and bad guys. MTV News has an exclusive look at what Gaga will look like when the movie hits theaters October 11.

Gaga transforms into Lady Chameleon in the campy action flick. And in two GIFs taken from the film, it's clear that Lady Chameleon means business — not only in the fashion department, but also in the bad-girl department.

One GIF features Gaga in a red outfit worn in the trailer, but the other shows us a new look. It features Gaga, throwing shade at the camera, wearing a strapless yellow number, a sparkling necklace and a fur throw.

The film, which includes a who's who of Hollywood A-listers, marks the singer's big screen debut.

The film also stars Carlos Estevez (a.k.a. Charlie Sheen) playing the president of the United States. Danny Trejo will reprise his role as Machete. Alexa Vega, Cuba Gooding Jr., Vanessa Hudgens, Sofia Vergara, Mel Gibson, Antonio Banderas, Jessica Alba, Amber Heard and Michelle Rodriguez are also in the film, the sequel to 2010's "Machete."

Gaga, who's droppingARTPOP a month after "Machete Kills," will team up with Rodriguez again when she makes a cameo in another one of his highly anticipated film projects, which is slated to hit theaters August 22, 2014.

Jimmy Kimmel is a funny guy. If you caught his show on Wednesday night, he ran a pretty funny skit spoofing Kanye West's epic one-hour BBC Radio 1 interview
.

He ribbed 'Ye for being his "own hype man" and questioned whether the "leather jogging pant" is really a thing. Because he couldn't understand much of what West was saying in the interview
, Kimmel hired a couple of kids to read the transcript (while sipping on milk shakes, of course), including a bit with 'Ye's most recent reference to his favorite movie, 


Well, you can guess how that went over. And you can probably guess ALL CAPS were involved. Like, many, many ALL CAPS.

"JIMMY KIMMEL IS OUT OF LINE TO TRY AND SPOOF IN ANY WAY THE FIRST PIECE OF HONEST MEDIA IN YEARS," West tweeted Thursday night.

Oh, and he was just getting started. "JIMMY KIMMEL, I DON'T TAKE IT AS A JOKE ... YOU DON'T HAVE SCUM BAGS HOPPING OVER FENCES TRYING TO TAKE PICTURES OF YOUR DAUGHTER," he continued. "JIMMY KIMMEL PUT YOURSELF IN MY SHOES ... OH NO THAT MEANS YOU WOULD HAVE GOTTEN TOO MUCH GOOD P---Y IN YOUR LIFE ... YOU CAN'T PUT YOURSELF IN MY SHOES. YOUR FACE LOOKS CRAZY ... IS THAT FUNNY? ... OR IF I HAD A KID SAY IT WOULD IT BE FUNNY???"

Things then got really real, when 'Ye asked if he should make a spoof about Kimmel's face, or about him "f---ing Ben Affleck," in reference to one of Kimmel's most ...

More often than not, on the first installment of The 20/20 Experience, Justin Timberlake proved to be an unreliable narrator, careening between the boastful bachelor and the blissfully betrothed, a man so in love with the institution of marriage that the mere mention of it had him jumping for joy on the cover of celebrity magazines.

The truth probably lies somewhere in-between, though, if you had a difficult time reconciling the sentiments of "Don't Hold the Wall" and "Let the Groove In" with those of "Mirrors" or "That Girl," you certainly weren't alone. If anything, the first 20/20 probably should have come with a neck brace; that's how severe the thematic whiplash was.

Luckily, Timberlake has rectified that problem on The 20/20 Experience -- 2 of 2 . This is not an album that spends an awful lot of time dwelling on the sanguine struggles of a committed relationship. Instead, it celebrates the thrill of the chase, and the exuberance of the conquest. It's a primal, pounding, passionate listen, from animalistic undertones (and actual animal noises) of opening track "Gimme What I Don't Know (I Want)" and the boudoir boasts of "Cabaret" (even though Timberlake's a professional, he likes to do his work at home) to the sex-as-bloodsport metaphors of and the sultry, spiky sonics of "Only When I Walk Away." Horns blare, guitars flare and the bass throbs. In short, there's no time for subtlety here ... JT's trying to get it in.

Which makes the second 20/20 a rather fascinating companion piece to the first; ...

Gleeks! It's here. Season five of "Glee" kicked off with reunions, second chances and — SPOILER ALERT — a proposal. And what better to way to start the very first episode than with the music of the Beatles.

The show started off with Rachel walking the lonely strip of 44th Street in New York City, looking at all the theaters she hopes to star in. Unfortunately, she hasn't made it yet, but this episode sets the scene for her chance in the Big Apple. Santana waitresses with her in a restaurant, giving a little sassy hope: "We can say we're working actresses." When Rachel serves the table of a man whom she had auditioned with, she vowed to prove herself to him. Which, in the "Glee" jargon, means breaking out into "A Hard Day's Night" in the middle of the diner.

Unfortunately, there was no Demi Lovato in this episode, but the teaser at the end looked particularly promising.

Meanwhile, back at McKinley High, things are going pretty well between Kitty and Artie — except one thing... Kitty wants to keep things on the DL. Sure, they're "official," and while Artie just wants to change his Facebook status (or hell, be seen together in public), Kitty has to keep up her cred with the Cheerios. In private, they sing "You've Got To Hide Your Love Away," but you'd never see them walking to class together.

With a boost from Tina, who blabs about the secret relationship in a New Directions rehearsal, calling the coupling "emotional abuse," Kitty finally comes clean, apologizes and ...

Wondering what it was like on set for Justin Bieber, Juicy J and Maejor Ali as they filmed the video together? It was as much the big party you'd imagine it to be.

Juicy broke down to MTV News what it was like to film the colorful clip, which features hot dancers and enough shots of a shirtless Bieber to keep his fans clicking over and over. "The video is super-amazing, man. We had a great time. We turnt up the whole time. [There was] a lot of energy, so I think the song is a smash," the Stay Trippy rapper dished. "I think it's going to do great."

Juicy can't say enough kind words about Bieber's work on the track. On it, instead of cooing about puppy love, the 19-year-old rhymes about swiping someone else's girlfriend. "I heard his verse [before I recorded]. He's got a dope verse," he said. "Justin Bieber is super talented."

Bieber is hardly the only pop star he's trading rhymes with. He also appears alongside Miley Cyrus on the Mike Will Made It track, on which she, too, is rapping. (Cyrus will be the subject of her own MTV documentary, , set to premiere on October 2.)

And Juicy is all about the current trend of pop stars trying their hand at the rap game. "I think it's just good music, just put out good music," he said. "When you get it on the radio, get in the clubs and the research comes back great, then you're good. It's going ...

She may have been The People's Princess, but there was much Diana, Princess of Wales, kept from the public's prying eye — intimate details catalogued in author Kate Snell's 2000 account "Diana: Her Last Love," the inspiration for the upcoming film starring Naomi Watts.

The film spans the final two years of Diana's life, before she — along with companion Dodi Fayed and driver Henri Paul — was killed in a car accident in Paris in 1997. At the center of "Diana" is the secret affair the Princess carried on with surgeon Hasnat Khan (played by "Lost" actor Naveen Andrews).

A new trailer for the biopic captures this clandestine romance, juxtaposed against the demands of Diana's high-profile persona. The clip opens with the Princess engaged in her royal and philanthropic duties — walking red carpets and crusading against land mines. But soon we see her meet Dr. Khan, telling him in no uncertain terms: "Charles and I live separate lives." Thus begins the under-the-table hand-holding, wig-wearing and secret rendezvousing, which, in a story familiar to us all, culminates in salacious tabloid headlines the world over.

And while her last beau, Fayed, is introduced in the clip's closing moments — and, as it's hinted at, used to make Khan jealous — it's clear Diana's love affair with the good doctor is the beating heart of this film.

"Diana," directed by Oliver Hirschbiegel and adapted by screenwriter Stephen Jeffreys, bows November 1.

Ke$ha's pissed. And she's letting everyone know it in her new music, including one song that rips into a thoroughly lousy ex-boyfriend ... and definitely hits below the belt.

"Right now [my new songs are] more dude-oriented, because I recently had this boy just be a total piece of sh--, douchebag piece of garbage [to me]," Ke$h vented. He's just a lying sack of sh--, balls, sh-- -filled b---sack, he's just a giant pair. And he has a tiny penis, and he sucks real bad, so I'm writing about that."

Yow. You'll notice that Ke$ha used the present tense whilst talking about her ex, which might lead some to believe that he's still (somehow) in her life. But, rest assured that is most certainly not the case.

"I blocked him, because he was being such a f---ing psychopathic piece of garbage dogs---," she said. "So I wrote a song called 'F--- You,' but then that title was already taken, so 'U Suck Ass' is another title. It's talking about fake orgasms every time I had sex with him, and how I pawned all the diamonds he bought me in Vegas and bought some Chanel earrings."

Will we see the target of all her ire on the upcoming second season of Ke$ha's Only time will tell. For the moment, Ke$h is content to let her ex squirm a bit ... turns out, Taylor Swift's got nothing on her.

"Don't f--- with me. Out of all the bitches to f--- with," she snarled. "I'll write a whole album and tell somebody in an ...
