Ke$ha knew she had found a kindred spirit in the Black Eyed Peas frontman will.i.am. So, when she was in the studio working on her latest Warrior single, "Crazy Kids," she wanted to get the song's co-writer to jump on the track, mostly because he provided the perfect verse for the celebratory jam.

"He and I wrote the song together, so it seemed like a natural thing for him to be on it, and his verse is really funny; he talks about boobies. Anytime somebody says anything about boobies, it's great — love it," the queen crazy kid herself told MTV News on Tuesday night when she sat down to premiere the visual for her latest Warrior single during

Sure, will doesn't physically appear in the video; instead a hologram of his face in an astronaut suit does while K parties with her real-life pet cat and bearded men. But Ke$ha and will's friendship had been solidified in the real world long before she shot the clip, when they were each working side by side in the studio.

"We were recording next door to each other, and we played this fun game that was, 'We're gonna play our music louder than the other one.' So by the end of the week, we both had just taken over the studio and we would go back and forth and take shots with each other and run around," she recalled. "He's like totally crazy also. And, you know, I feel like we just really vibed with each other. He's really positive ...

On Tuesday night's episode of "The Voice," eight became six as the remaining contestants discovered who would be moving on during the show's live eliminations.

Before saying goodbye to two singers, viewers said hello to Sheryl Crow as she treated fans to her newest single "Easy." The nine-time Grammy Award-winning singer has shared the stage with everyone from the Rolling Stones to Michael Jackson but it was Blake Shelton's team that joined her during this very special performance of the song.

Dueling Duets
And the collaborations didn't end there. Between results, opponents were paired up for an evening full of duets. It all kicked off with Michelle Chamuel and Judith Hill's rendition of Calvin Harris and Florence Welch's "Sweet Nothing" and was followed by other noteworthy performances including the Swon Brothers and Sasha Allen's cover of Jason Aldean and Kelly Clarkson's "Don't You Wanna Stay" and Danielle Bradbery and Sarah Simmons' performance of Christina Perri's "A Thousand Years."

Four Eyes on the Prize
After rocking Michelle Chamuel's trademark black-rimmed glasses during Monday evening's live rounds, Usher paid homage to his last contestant on Tuesday by donning the specs again. And it wasn't just her coach who was getting in on the action either. After learning Chamuel would be moving on in the competition -- "It's crazy! I'm just very, very grateful! Thank you so much," she said -- Social Media Correspondent Christina Milian shouted out Usher's innovative hashtag (#4eyesontheprize) and then slipped on a similar pair of bifocals.

Voice Confessionals
Results weren't the only thing revealed Tuesday night. All four judges and ...

Amanda Bynes has a burgeoning side career as a Twitter warrior. The troubled actress, who is awaiting a July court date in connection with last week's alleged bong-tossing incident 
 in New York, fired up two fresh Twitter beefs on Tuesday after receiving unsolicited advice from a model and one-time rock icon.

"The fact that Amanda Bynes has any 'support' to retweet is really unsettling ... Support people with mental illness, yes. But don't condone/enable scary and poor behavior," wrote Sports Illustrated model Chrissy Teigen.

Bynes, who has thrown Twitter jabs at everyone from Rihanna 
 to Jenny McCarthy, Jay-Z and Drake, did not take that advice kindly, hitting back, "Ur not a pretty model compared to me. I signed to Ford models @ age 13. I don't look up to u beauty wise. I'm far prettier than u! I'm offended that you're saying I have a mental illness when I show no sign of it, but thankfully not one man that wants me wants you and you are an old ugly model compared to me!"

And she wasn't done. Adding, " You look 45!," Bynes said to the model, who, like her, is 27. "You're not pretty so I'm not intimidated by you! I think you're jealous that you're just an ugly model whos career is uninspiring! I don't respect you! You're no beauty queen! I'm a beauty queen!" Teigen declined to be dragged into a fight, though, writing, "Nope. Not going to indulge. Wish the best for her, truly," asking her followers to do ...

Jamie Campbell Bower is here to prove that not every Prince Charming is, well, charming.

In his upcoming film Campbell plays the always snarky, rarely snuggly Jace Wayland, a demon-destroying Shadowhunter and the love interest of Brooklyn teen Clary Fray (Lily Collins).

When MTV News visited the set of the urban fantasy (based on the best-selling novel by Cassandra Clare), the actor was quick to affirm that while his character is something of a jerk, it's a role he's relishing.

"What I love about him is the fact that he's actually a bit of a douchebag," Bower said during a 3 a.m. interview on the Toronto set. "He's not like a meathead, he's just sarcastic and rude."

And for good reason, as fans of the series can attest. Jace has a complicated background (one we'll leave vague to avoid spoilers), but suffice it to say, this history has gone a long way towards making him the oft-prickly character he is today. Bower commended director Harald Zwart for capturing not only Jace's moodiness, but that of the monster-ridden world in which he and his fellow Shadowhunters exist.

"I think there is a darkness that Harald has brought to the piece that is easily lost in adaptations, particularly of YA novels," Bower said. "And there's a reality to it, as well, which is nice. You know, it's very easy to go into fantasyland too quickly — he says wearing a dress, effectively. Every girl's got to have a little black dress — that's how I look at it."

Of course, it takes a lot more ...

While you were lounging at the pool or grilling up some dogs over Memorial Day weekend, Amanda Bynes was busy prepping lawsuits, threatening Rihanna and romancing fellow Nickelodeon child star Drake Bell.

The action came after the actress was arrested
 by the New York Police Department on Thursday for allegedly throwing bong out of her 36th floor apartment window following reports that she was smoking marijuana in the lobby of her building. That set off a series of odd incidents over the weekend that included her threat to file a lawsuit against the NYPD.

A run-down of Bynes' latest
 wild weekend:

»Saturday: Bynes tweeted to her fans not to believe the "lies" about her arrest, claiming that officers were inappropriate during the incident. "I was sexually harassed by one of the cops the night before last which is who then arrested me," she wrote. "He lied and said I threw a bong out the window when I opened the window for fresh air. Hilarious. He slapped my vagina. Sexual harassment. Big deal. I then called the cops on him. He handcuffed me, which I resisted, quite unlike any of the reports stated."

She added that her trip to a mental hospital before processing was "offensive" and that the police acted "creepy" and that they didn't find any pot on her or any bong
 outside her window, which is why the judge released her on her own recognizance. An NYPD spokesperson said the department is investigating Bynes' claims. Amanda also told her million-plus followers to "believe everything I say on ...

Break out your vintage homemade signs and t-shirts, the Package Tour kicks off this week. And with the New Kids on the Block, 98 Degrees and Boyz II Men ready to belt out some of their biggest hits, it's bound to be every fan's dream.

It all kicks off Tuesday (May 28) in Uncasville, Connecticut, and will circle around North America, before wrapping up August 4 Indianapolis, Indiana. 98 Degrees are pretty stoked to be in the middle of a BIIM and NKOTB sandwich night after night.

"Well, we like to say, if New Kids on the Block and Boyz II Men had a child, it would be us," Drew Lachey told MTV News of playing second every night. "We kind of, in a lot of ways, took our inspiration from Boyz II Men — their harmony sound and things like that — [and] obviously New Kids On The Block, the way they pioneered the genre. So it really is just an honor to be on this tour in general. We said this tour is all about the fans coming out, giving them a fantastic show. It's gonna be basically three hours of hits. It's our job to come out and make sure you leave with a smile on your face."

Nick Lachey added, "We feel like we're part R&B [group] and we ended up being part boy band. We were kind of caught in the middle, so it's almost symbolic that were sandwiched between these two groups on this show." (Each night BIIM will take the stage first, ...

Emeli Sandé's "Next to Me" is one of the most inescapable songs of the moment. The lead Stateside single from Sande's debut, Our Version of Events, has quickly landed her on the pop A-list.

Needless to say, it's been quite the whirlwind for the 26-year-old former med student. "That was a big breakthrough single for me back home in the U.K. Things change a lot when people listen to your music and your life completely changes," she told MTV News. "So the past two years have really been a fast ride for me."

In fact, the feel-good ditty has even given her the kind of recognition that leads to calls from showbiz heavyweights like Jay-Z and Baz Luhrmann, who enlisted the Brit R&B singer to cover Beyonc—'s "Crazy in Love" for soundtrack.

"It was initially quite daunting, especially because Jay-Z is the executive producer," she said of re-recording Bey's single from her 2003 solo debut, Dangerously in Love, with Roxy Music's Bryan Ferry. "But [it's] a big honor to be involved, and it was really, really fun going to the premiere and seeing it all come together."

Listen To Emeli Sandé's Version Of 'Crazy In Love'!

When we caught up with Sandé earlier this month, she had yet to hear from the Queen Bey about her cover, but did get the approval of her hubby. "I haven't met Beyoncé, but I met Jay-Z afterwards and he was digging it," she said. "So that's good."

Next up, Sandé is working out what her next single will be, and she promises it's ...
