Ke$ha covers V magazine. (Inez van Lamsweerde & Vinoodh Matadin)Ke$ha has always fancied herself not-your-typical conventional pop star. After all, half the time she looks like she just crawled out of a glitter-lined gutter. But in a new interview with V magazine, she reveals her dream collaborations and shockingly one of them is the world's most famous, most mainstream pop singer: Justin Bieber. "The range of artists I want to work with is so vast it's bizarre," she tells the mag for its May "Americana" issue. "I would love to have [Rolling Stones guitarist] Keith Richards on the record. I would sure as hell like to do a collaboration with Bieber and at the same time do a song with [experimental rock band] the Flaming Lips. If someone is a real artist, you can't confine them to a particular genre. It's my mission to make it all make sense somehow."

The R&B star debuted his limited-edition toy and sculpture line with famed artist Ron English, called Dum English, on Wednesday at Toy Art Gallery in L.A., and then showed off his contemporary pop art later that night at the Corey Helford Gallery. At the exhibit, the creative duo even tag-team painted a life-size astronaut sculpture for the guests in attendance.

Dressed in white and black pants that allowed her to shimmy, she sang "Good Girl" and "Cupid's Got a Shotgun" off her new album Blown Away, as well as her past hit "Cowboy Casanova."

If you can't beat 'em, join 'em. That seemed to be Rihanna's motto over the weekend while vacationing in Hawaii, where she found herself (surprise, surprise) trailed by a gaggle of paparazzi on the beach.

Determined to get their shots, the pesky paps followed the "Disturbia" songstress — who was donning a cowboy hat and itsy bitsy bikini — into the Pacific, where Rihanna approached one of the photographers and grabbed his camera. After a friend snapped a pic of the in-water incident, Rihanna tweeted it out to her more than 18 million Twitter followers with the note, "Me high jackin the PaPz."

Selena Gomez (Angel Delgado/Clasos.com/LatinContent/Getty Images)Selena Gomez has often spoken about her namesake, the late Tejano singer Selena Quintanilla-Perez, known simply as Selena. But on a new tribute album, Gomez actually gets to sing with her! The 19-year-old recorded a duet of Quintanilla-Perez's song "Bidi Bidi Bom Bom" for the Selena tribute album, Enamorada De Ti, released this month. "I was completely honored when they asked me to be on the tribute CD," Gomez told JustJared.com. "And when I went into the studio to record they actually had her vocals in the booth that she was in, so I felt like she was singing right next to me. It gave me chills! It was incredible and it was a great experience and it was a great song."

What do Justin Bieber and The Wanted have in common — besides being crush-worthy young singers, of course? They both have been snubbed by Christina Aguilera on "The Voice." The same night the blonde made a face when Bieber gave her a hug (after she coldly offered a handshake) during his appearance on the NBC singing competition to preview his "Boyfriend" video, the Irish boyband also came on the show to perform. And they were greeted with a similar chill. "She was a total b---h," Tom Parker said during radio station NOW FM's interview with the "Glad You Came" singers. "She just sat there and didn't speak to us. Wouldn't even look at us."

What better place to renew your vows than in Paris? That's exactly what Mariah Carey and hubby Nick Cannon did to celebrate their fourth year as husband and wife on Friday, three days before their actual anniversary, April 30 -- which also happens to be the first birthday of their twins Monroe and Moroccan. With the Eiffel Tower as their backdrop, Carey -- in a white satin mermaid-style gown with a black bow -- beamed as a white suit-clad Cannon got down on one knee, took her hand, and looked into her eyes during the intimate ceremony at La Maison Blanche hotel.Before they jetted off to the French capital, the "America's Got Talent" host hinted that he and his superstar wife were planning something "special and unique" -- and it looks like they achieved their goal with the lavish celebration.

Ke$ha (Getty Images for Versace for H&M)Oh, Ke$ha!

Celebrities are notorious for oversharing. We've heard Jessica Simpson discuss her issues with flatulence, the Kardashians reveal what they do with mayonnaise and Kendra Wilkinson talk about having sex on a jet ski. So the fact that Ke$ha tweeted a photo of herself going to the bathroom really shouldn't be that big of a surprise, should it?
