Al Bello/Getty ImagesAnd we thought he was a lover, not a fighter. Justin Bieber made a perplexing appearance at the Floyd Mayweather-Miguel Cotto boxing match on Saturday night — but he wasn't just a spectator. The "Boyfriend" singer escorted Mayweather to the ring for the fight at the MGM in Las Vegas, draped in two of the champ's belts, alongside rappers 50 Cent , Lil Wayne, and 2 Chainz. After Mayweather beat Cotto in 12 rounds, the 18-year-old was back in the ring to celebrate his win. Although the twosome may seem like an odd couple, according to reports Bieber and Mayweather are not only great friends, but the boxer has become a "mentor" to the teen — even though he has been charged with domestic violence against four women since 2002, and was arrested in 2010 for threatening to beat his own children if they called police after he punched their mother repeatedly in front of them.

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."

Kutcher and Moore in happier times. (Jim Spellman/WireImage)Demi Moore is no longer Mrs. Kutcher in more ways than one. On Thursday — nearly six months after she and Ashton Kutcher announced their split — the actress finally changed her Twitter handle from @MrsKutcher to @JustDemi. "So hard finding a name that was fun somewhat playful and available," she wrote on the social network. "It could grow on me! … Thanks everyone for your help in finding my new name!"

Brown autographing a toy. (Alexandra Wyman/WireImage)We already know Chris Brown can sing, dance, throw chairs, and sell puppies — but were you aware he's an artist, too? 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.

Brown with Bobbi Kristina in February. (Perez/X17online.com)Like mother and father, like daughter? Bobby Brown opened up about his only child with Whitney Houston, Bobbi Kristina, during the second part of his interview with the "Today" show's Matt Lauer on Thursday morning, and the singer admitted that he is concerned the 19-year-old will follow down the same path of substance abuse as her parents. Even before Houston's February death, which was ruled as a result of her cocaine abuse, Bobbi Kristina has reportedly had issues with drugs. Last March, she was photographed snorting what appeared to be cocaine — which she claimed was a set-up by an ex. "I would always be worried about that," Brown, who was arrested for DUI in March, revealed to Lauer, but added it wasn't a current concern "because I know … I know what she is actually doing."

Kaia, Cindy, and her mother Jennifer. (JCPenneys)Talk about three generations of beauty! Cindy Crawford stars in a sweet Mother's Day ad campaign with her mother Jennifer and 10-year-old daughter Kaia Gerber for JCPenney. In the photo, all three ladies are casually dressed in jeans and white tops from the department store and appear to be laughing about something, as the supermodel links arms with her mother. "Oh my goodness, she's just the best mom in the world," the adorable little girl — who is the spitting image of her mother — says about Crawford in the accompanying video. "She's so nice, and I can actually hang out with her and have fun."

Johnston. (Donna Ward/Getty Images)And we thought Hollywood was the home of weird baby names. Thanks to the Palins — and Bristol's baby daddy Levi Johnston — Wasilla, Alaska, is giving Tinseltown a run for its money. The latest addition? Breeze Beretta, the unborn daughter of Johnston and his new girlfriend Sunny Oglesby. The baby will become the half-sister of Johnston and Palin's 3-year-old son, Tripp, and, for those taking count, the Palin family also consists of Track, Trig, Willow, and Piper, in addition to Johnston's sister Mercede.

Simpson spared no expense for Maxwell's birth. (Jamie McCarthy/Getty Images)When Jessica Simpson delivered her nearly 10-pound baby girl Maxwell Drew Johnson on Tuesday morning, she did so in the lap of luxury. The singer-designer reportedly rented out a sweet $3,784-a-night three-room, two-bath suite at Cedars-Sinai Medical Center in Los Angeles — big enough to house fiancé Eric Johnson and his family, her parents, sister Ashlee, and their many well-wishers. And when they're not all cooing over the little girl, everyone can entertain themselves with the room's amenities: a flat-screen TV and DVD player, stereo, refrigerator stocked with bottled water and juice, baskets of fresh fruit and muffins, hotel-style robes, salon services, and gourmet meals made-to-order.
