In the much-anticipated 100th episode of which airs Tuesday, Gleeks will not only witness the reunion of some former castmates, but will be treated to a familiar face: former "Gossip Girl" star Chace Crawford.

In a behind-the-scenes teaser released Monday (March 17) for the upcoming episode, Chace introduces us to his character, Biff McIntosh, the preppy, snobby boyfriend of former head Cheerio, Quinn (Dianna Agron).

"I play her douchey boyfriend from the Northeast, so it's more of a character. It was a good time. [I did] four or five scenes; we had a blast," Crawford recently told MTV News.

Quinn brings Biff, who she met at Yale, home to her former stomping grounds at William McKinley High School, and let's just say he didn't make a great first impression.

"I haven't spent that much time around them, but poor people are generally less attractive than rich ones," Biff says in a scene from the episode.

Biff, who Chase describes as "quite obnoxious" and "a jerk," is in fact, in for a rude awakening, since Quinn conveniently forgot to mention her somewhat-erratic past.

"He knows nothing about her real life," Agron said. "And she's kind of sugarcoated everything."

So, what kind of skeletons come out of Quinn's closet? Well, after Biff, who Crawford revealed will not be participating in any songs during the episode, asks Santana to describe Quinn in one sentence, she decides to throw Quinn under the bus and divulge on her not-so-proudest moments.

"She died ...

The 1975 swept through Austin, Texas this past weekend for their second-straight South By Southwest fest ... and their first appearance at the mtvU Woodie Awards.

And though plenty has happened to the breakout Brits since their first trip to SXSW — including their — let's just say that first visit is one they won't forget any time soon.

"Last year we were renting a house off some baseball star who was really religious, and his mom turned up and found lots of, like, paraphernalia, and found out we'd been sharing a bed — three guys — and they called us 'Godless animals' and they chased us out of the house with a gun!" frontman Matt Healy laughed. "They didn't like it! I was like 'Come on! I thought we were in Austin! I didn't think this was, like, hick territory.' They hated us."

"They thought we were being gay in their bedroom or something," drummer George Daniel added. "And then one of our friends, he didn't even know this had happened, he was still at the festival, he went back to the house and had a shower, and managed to leave without them even leaving! It was brilliant!"

Of course, given that their plans for 2014 include "not dying," you'd think the 1975 would want to avoid Texas for the foreseeable future ... but they'll be back in May for a trio of shows as part of their seemingly endless world tour. And, no, they're not worried about any gunplay this time around.

"We've done so many countries, ...

When Lil Wayne dropped his original Tha Carter LP in 2004, he was just 21 years old, taking on the role of Cash Money Records' flagship artist after the departure of former label stars Juvenile and B.G. Ten years later, the rap veteran is prepping Tha Carter V and is ready to put a decade's worth of life lessons into what he says is his final solo album.

"I say it's different, because I'm older and wiser, and I know more things and I know more about myself now," the decorated rap star told MTV News as he leaned back on the couch of his trailer Wednesday morning during a break from shooting Young Money's "Senile" video in Los Angeles.

Through the years, Weezy has grown from a kiddie rapper to a respected lyricist, mostly due to his free-associative rhyme style, in which he connects unrelated thoughts with creative one-liners. On his 2010 single "6 Foot 7 Foot," Tunechi peppered his verses with references to baseball, sex, He-Man and synchronized swimming. He also reminded us that "Real Gs move in silence like lasagna."

Unfortunately, that same off-the-cuff style landed the Young Money boss in some controversy last year when he delivered lines about civil-rights figure Emmett Till on Future's "Karate Chop" remix. Weezy eventually apologized, but lost an endorsement deal with Mountain Dew and was became at odds with the Till family as a result.

"I'm more careful about what I'm doing and trying to be more careful what I'm saying," he explained about his state of mind while recording ...

The Kanye West-inspired soundtrack, which was released last week, features a mix of hip-hop and EDM hits that completely encapsulates the moods, feelings and emotions of the characters and the scenes.

There is one artist that holds it all together, and that is Ellie Goulding. The pop star's songs take the film's pivotal scenes to new heights, with playing over the final scene in the movie, and "Dead in the Water" perfectly heightening the emotion in the much-anticipated kiss scene.

"I've always loved the idea of doing a film soundtrack, so when ... I'd seen the film and they put some of my songs to it, my face lit up. I felt very excited," Goulding said during after the premiere of her video for "Beating Heart." "It's the first thing I've done where my voice is used amongst the soundtrack rather than just songs."

Director Neil Burger said that Goulding acts as the inner voice of Tris, played by Shailene Woodley; her voice is heard woven throughout the film's score.

Music supervisor Randall Poster recently told MTV News that if he returns for the series' next film, "Insurgent," he would love to "maintain Ellie as the voice of Tris."

"Everyone might get a bit annoyed with my voice. I would love to ...," Ellie said about joining the next soundtrack. "I would like to do stuff that's a more bit out of my comfort zone and a bit different. I make a lot of pop music that's my true love, but yeah, I'd love to ...

There's a new Rihanna song on the Interwebs, but it's not by Rihanna. Sia originally penned the track "Chandelier" for the likes of Ri, but, in the end, she decided to keep it for herself.

"I usually think, 'Oh this would work for Rihanna, or this would be a good one for B or Katy,'" Sia told "On Air with Ryan Seacrest." "But this time I was like, 'Uh oh I think I just wrote a full-blown pop song for myself by accident!'"

"My friend Jesse Shatkin and I were jamming in the studio — I was playing piano and him on the marimba — and this gem popped out," she said.

The track is a kind of sad, modern-day Gatsby jam about the glitter and fatigue of a party girl's life, capped off with Sia's soaring refrain: "I'm gonna swing from the chandelier."

The song is Sia's first original track since 2010′s We Are Born, although she did contribute a song to "The Hunger Games: Catching Fire" soundtrack last year with Diplo and The Weeknd.

I, for one, hope that this new song heralds new music from the singer-songwriter, a prolific talent who has been penning songs since the '90s for the likes of Rihanna, Christina Aguilera and Flo Rida.

"She's been incredible for a long time," collaborator Ne-yo told MTV News last year of Sia. "Her mastery of melody, from just the way that she works, her words and phrases, it's been incredible. And people are just now catching on! Y'all are late; everybody's late. It's been that way."

We've seen him pull devious tricks as pissy little brother/god Loki in Marvel's "Thor" franchise, and he's popped up in numerous roles from "War Horse" to the upcoming "Muppets Most Wanted," but we've never seen Tom Hiddleston as a jolly, singing pirate before.

That's just what he voices in "The Pirate Fairy," Disney's new straight to DVD/Blu-ray animated creation tracking the misadventures of a fairy, voiced by "Mad Men" star Christina Hendricks, who steals some magic pixie dust and teams up with pirates along the way. Hiddleston voices a young, pre-hook Captain James Hook.

While we'll have to wait until April 1 to witness the full glory of this star-filled endeavor — beside Hiddleston and Hendricks, the movie also boasts the vocal talents of Lucy Hale, Megan Hilty and Anjelica Huston, among others — Disney released a featurette with footage of Hiddleston singing in-studio alongside actual animation from the movie.

"They're all kind of dreaming of all the places that they're going to pillage and plunder," Hiddleston says in the clip of the song, which he sings lead on, backed up by, of course, a chorus of pirates.

"Hook knows he's bad," Hiddleston said of his character. "He relishes being a pirate and having kind of these huge ambitions to steal and plunder. As a child you're partly afraid of him, but you partly love him."

So...Pirate Loki? It's gonna be a while before we see him back in that dark, stringy wig again, so we'll take what we can get.

He's Hollywood's next "It" guy, with handsome charm, a hilarious personality and the talent for busting some dance moves. Miles Teller can do no wrong, which is why he is MTV News' pick for this week's Man Crush Monday.

Miles will next been seen playing bad boy Peter in but he first danced his way into our hearts during the remake of "Footloose." He showed us his party side during "21 & Over," had a bit of an "Awkward Moment" with Zac Efron and had us falling in love during "The Spectacular Now."

Most important of all, Miles definitely knows how to kiss. I don't speak from personal experience, but we wouldn't have nominated him for an MTV Movie Award for Best Kiss if he wasn't any good.

Need some more convincing as to why Miles is our #MCM? Well, take a look at the GIFs below, which will no doubt cheer up your Monday blues.

It's Getting Hot In Here...Time To Cool Off

Miley Cyrus spent the first month of the Bangerz tour creating a controlled chaos that left us wondering

Now, as the trek enters month number two, she's forged a friendship with a fellow Fearless Freak, Flaming Lips' frontman Wayne Coyne ... and, once again, all we can do is wonder what the heck is happening.

Yes, it all started on Friday (March 14), when Coyne posted a pic of Cyrus rolling a joint — using custom Bangerz papers, of course — on his Instagram account, telling the world that the two were "recordin" together ... and that they were "high as f---" (an important detail.)

That was followed by another photo of Miley in a vocal booth, "vomiting diamonds" (according to Coyne) while singing the Beatles' "Lucy in the Sky with Diamonds."

The collaboration, which presumably took place around Miley's show in Tulsa, Oklahoma (the Lips hail from Oklahoma City), followed an earlier appearance by Coyne at the Bangerz stop in Los Angeles, where he joined Cyrus onstage to sing the Lips' "Yoshimi Battles the Pink Robots."

Of course, it's not exactly clear where the cover of "Lucy in the Sky" will end up ... a rep for the Flaming Lips told MTV News that everything is still in the "preliminary planning stages." But that didn't stop Miley from preserving the moment for posterity as only she could: by getting a crying kitty tattoo insider her lower lip.

Coyne — who has previously recorded with another pop oddity, Kesha — showed his mutual admiration by ...
