It's New York Fashion Week, and that means that the biggest celebs are hitting up the Big Apple to take a bite out of the runways' freshest fashions. As designers pull out all the stops to show off their Spring/Summer lines, stars sit front row. At after-parties, they mix and mingle with supermodels and pricey duds. Want to know where some of your favorite celebrities have been spotted? MTV News has rounded up some of the biggest names at the event.

Let's Hear It For The Boys
Justin Bieber was spotted at two fashion shows this year, including the Opening Ceremony Spring 2014 show, which was also attended by Miguel, Rihanna and "Parks and Recreation" fashionista Rashida Jones. Later on, Bieber was also spotted in all black everything at the Y-3 show.

Fellow male fashionista, Kanye West, also made the rounds this fashion week popping up at Hood by Air and also Alexander Wang, where he was photographed hanging out with famed photographer Terry Richardson (who just directed Miley Cyrus in her "Wrecking Ball" video). Meanwhile, the Jonas Brothers made some time to check out several shows and got goofy at parties.

Girls On Film
Nicki Minaj never met a bandage or bodycon dress she didn't love, and she was spotted at Herve Leger peeping some of the latest looks from the iconic fashion brand.

Rihanna was not only photographed at Opening Ceremony, but she also made time to catch up with Alexander Wang at his ...

Eminem and Kid Rock have repped hard for their hometown of Detroit for years. But other than a Slim Shady cameo on the 1998 song "F--- Off" from Rocks' breakthrough Devil Without a Cause album (just before Em blew up solo), the pair have almost exclusively flown their D-Town pride from frinedly, but neutral corners, rarely appearing or performing together.

That's all changed in the official video for "Berzerk," the first single
 from Slim Shady's highly anticipated upcoming The Marshall Mathers LP 2
.

We got a teaser look at the clip on Saturday night
 during Marshall's unexpected drop-in at ESPN's College Football Prime Time, but on Monday (September 9), the full video dropped and it had plenty more surprises in store.

A kind of mash-up of Beastie Boy visual call-backs, "Jackass" and "Bum Fights"-style snippets and cameos from some of Em's pals, the finished product definitely finds Slim Shady back in his playful old groove. As we saw in the teaser, the opening mimics the blue screen from an old-school VHS tape, before cutting to Em's hand putting down a giant boombox with the word "Beats" scrawled on the cassette carriage.

As the camera pans out, we see a two story master blaster that towers over Shady (in white t-shirt, khakis and his signature bleach blonde hair) and super-producer Rick Rubin (in all black and barefoot) approaching the fish eye lens.

A smash cut shows the rapper in a T-shirt featuring Run-DMC and the Beastie Boys, the first groups to use the hard rock-meets-rap sound that Rubin pioneered with Def Jam ...

Academy Award-winner Kate Winslet is entering new territory with her role in the dystopian drama — namely, Franchiseland. But don't use the "f word" around the 37-year-old actress.

"It's funny. I think I'm developing a kind of subconscious loathing of the word 'franchise,' " she told MTV News' Josh Horowitz while promoting her movie "Labor Day" at the Toronto International Film Festival. "I just think of something that's packaged, something you can buy on a shelf and is immediately disposable. I don't know. It's a really weird word for me."

Winslet's distaste for the term, however, didn't stop her from accepting the role of Jeanine Matthews in the film based on Veronica Roth's best-selling novel, which takes place in a society divided into five factions, each representing a different virtue.

"I didn't have any hesitation at all," she said of her role in what could be a three-part series. "It was such a great script. It's a fantastic book."

In fact, her part in the project has already earned Winslet a modicum of cool cred with her kids.

"My daughter is going to be 13, and my son is almost 10, and they're getting to that age where this is the type of literature they're going to be reading very soon," she explained. "In fact, my daughter, two days ago, came home from school and went, 'Mom! You're never going to believe it. Rufus came up to me at school and said, 'Is your mom really in 'Divergent'? Is there going to be a premiere? Can you get me a ticket?' ' ...

In Miley Cyrus's new "Wrecking Ball" video, she suggestively licks a sledgehammer and writhes nude atop a wrecking ball ... two scenes that, in any other context, certainly would rank right up there on the scandalous scale.

Then again, this is Miley, and fresh off her twerk-tastic VMA performance, she's seemingly lost the ability to shock us with her antics. So, in a bizarre twist, it's somewhat fitting the most jaw-dropping moment of her new video is also the most straightforward: the opening scene when a fresh-faced Cyrus stares directly into the camera, a single tear tracing its way down her face, and just sings.

It's an image that calls to mind Sinead O'Connor's iconic video, and it's starting in its simplicity. For all that's been made of Miley's VMA moment — and her unrepentant attitude in the aftermath — we sometimes forget that she is still; a) just 20 years old (though perhaps that's the point), and b) capable of genuine emotions.

Here, both of those things are readily apparent, and stripped of everything salacious, we are left with the reminder that Miley is actually a very capable performer, the kind of singer skilled enought to tackle emotive songs like Bob Dylan's "You're Gonna Make Me Lonesome When You Go" or

Of course, most folks will miss that point, and instead focus on the scenes where she strides around in her underwear, tongues tools and takes a naked ride on a wrecking ball. That's to be expected, given the sheer amount of media attention ...

For the past month, Arcade Fire have slowly been rolling out clues about their new album, first with a mysterious "REFLEKTOR" tag that's subsequently been spray-painted around the globe, then, a message to tune in at 9 p.m. on September 9, for the worldwide-premiere of the Anton Corbijn-directed "Reflektor" video, and finally, a rather dramatic (and shiny) rebranding as "The Reflektors."

So, you can imagine their disappointment when, less than 72 hours before "Reflektor" was set to debut, the song leaked. It seems someone took it upon themselves to rip the track from limited-edition 12" that was set to go on sale today — this is why we can't have nice things, people! — and though the grand unveiling didn't quite go as they'd planned, we're willing to bet that somewhere, Arcade Fire are delighting in the discussion their brand-new single is creating.

Because, "Reflektor" certainly represents a new direction for the band ... with its slipstream synthesizers, constant conga beat, four-on-the-floor focus and heavy horn section, it showcases a dancier side of the oft-serious art rockers.

Of course, it's still plenty dark, too — with Win Butler keening "Trapped in a prism/In a prism of light/Alone in the darkness of White" (lyrics that were, in part, revealed on the back of the "Reflektor" 12") and his wife Regine adding the odd, ethereal line in French — not to mention a cameo from David Bowie, whose voice adds a dour tone to the proceedings.

The song also doesn't seem to stray far from many of the subject ...

Of course Uncle Jack and the white supremacists were going to show up! The bullet-ridden finale had the kind of inevitability that made Sunday night's episode of "Breaking Bad" so difficult to watch without covering your face with your hands.

Next week's episode is a little harder to predict thanks to the cruelly perfect timing on the cliffhanger. The only person we know who walks away from the shootout in "To'hajiilee" is Walter. Everyone else could potentially be taking a dirt nap not far from Heisenberg's buried barrels of money, but we've got some guesses as to who that might be.

Steve "Gomie" Gomez - 1 to 5 There's no way that that many bullets get fired and someone doesn't die, and when that many white supremacists point their rifles and an automatic shotgun at the DEA agents, at least one of the good guys is going down. With Marie fully aware of the secret mission to bring down Walt, Gomie is fully expendable. He's enough of a minor character to die without it being too much of a downer, and his death would be enough to force Walt to leave New Mexico. Sorry, Gomie. You were an OK cop.

White Supremacist Kenny - 1 to 3 Uncle Jack's buddy (and, like Jesse Plemons, a "Friday Night Lights" alum), Kenny is without a doubt the Gomie of the white supremacists. Someone needs to die from each side to show that the shootout was actually deadly instead of the miss-a-thon that we saw at the end of this episode. If Hank or Gomie are ...

Bruno Mars has been big time for a while. But over the weekend the 
 singer landed the most mega gig there is: the Super Bowl halftime show. The Hawaiian native will log some serious frequent flier miles next year when he begins rehearsals for the February 2 game at MetLife Stadium in East Rutherford, New Jersey.

The Grammy and VMA-winning singer will join a list of recent megastars who've played the gig, including: Beyoncé
, U2, The Who, Madonna, Paul McCartney, the Rolling Stones, Prince and, in 2009, Jersey's own Bruce Springsteen.

And while the announcement of his addition to that roster has caused a bit of rumbling from some disgruntled Jerseyites who are mad that organizers didn't choose amore Tri-State appropriate act, we here at MTV think there's plenty of room for Mars to pay tribute to the New York/Jersey area while still doing his thing.

Here's a list of our dream collaborators for the Super Bowl XLVIII halftime show.

Wyclef Jean/Lauryn Hill: First the good news: Hill will definitely be done with her prison sentence for tax evasion
 by the time the Super Bowl comes around. And though her "Neurotic Society" single was a failed comeback attempt, there is nothing more Jersey than getting her to finally reunite with fellow South Orange native Wyclef Jean for a mini Fugees reunion, with Mars acting as the pop peanut butter holding that fragile sandwich together.

Bon Jovi: Let's face it, a lot of people though that Jon and the boys were a shoo-in for this job. I mean, what's ...

Lady Gaga is no stranger to unforgettable performances. And on Monday (September 9) she added one more to her long list of stage spectacles. She took the stage on "Good Morning America" to put a very old Hollywood spin on her latest single, by paying homage to the 1939 Judy Garland classic, "The Wizard of Oz."

Wearing a blue-and-white gingham dress like Dorothy's, she first performed "Over the Rainbow" with her real dog, Fozzi, serving as a Toto stand-in. She sang the track to the Scarecrow, the Cowardly Lion and the Tin Man (who would later serve as her back-up dancers) before declaring, "Well, I live for your applause. Shall we make our way to Oz?"

The theatrical performance included audience members wearing poppy hats and, of course, a yellow brick road. At one point she changed out of her Dorothy attire to rock a Glinda the Good Witch dress and then stripped down to her black to defeat the Wicked Witch of the West. It was all capped off when she re-emerged in her Dorothy gingham with big hair and a bow.

Gaga was back after her eye-catching performance of "Applause" to chat about why she wanted to pay homage to the iconic flick, which is celebrating its 75th anniversary. "I think it really is an explanation, in a way, for my entire career so far, even with the VMAs performance and then the transformations that were happening today," she said. "It's like my way of saying all of these outfits and all of these wigs ...
