Hew Burney for Hard Rock Hotel & Casino

The party never ends for Chris Brown!

After celebrating with Diddy in Las Vegas over the weekend, we later snapped the 23-year-old R&B star taking the stage at the Hard Rock Hotel & Casino's Paradise Pool for Kandy Vegas. He certainly knows how to heat up a show!

The following day Chris was spotted partying poolside while Jersey Shore alum DJ Pauly D spun some tunes at the Rehab Sunday Pool Party ... sounds like a blast!

And by boys, we mean sons Kingston and Zuma AND her No Doubt bandmates!

Gwen Stefani touched down at JFK International Airport in New York City last night, and even she seemed surprised by all the attention she received from fans and photographers. She better brace herself -- we have a feeling there's going to be a lot more chaos in the days leading up to the September 25 release of the band's new album Push and Shove. After all, we haven't heard new tunes from them in over a decade!

Gwen covers the new issue of Elle UK, and when asked about the inspiration behind the new record, she said, "[The album is] about being overwhelmed and the balancing and trying to do all of it."

Sounds like that's relevant to other areas of her life as well!

Justin Bieber loves nothing more than getting inked!

The "Boyfriend" singer recently added another tattoo to his growing collection in the form of a tiny crown on his upper chest, and what better way to share the new body art with fans than taking shirtless pics and posting them on Twitter!

Sprawled out on a bed, the 18-year-old teen sensation posted these pics with the caption, "New tattoo its a crown if you couldn't tell." Usher's protege already has a Japanese symbol, the word "Believe," a bird, praying hands, and the word "Jesus."

"Im thinking to myself 'wow really justin 3 shirtless pics in 3 days' who do i think i am a young @Mark_Wahlberg sheesh lol," he added.

We're sure his legions of lady admirers don't mind at all!

Studded boots, skinnies ... and an exposed white bra? Yikes!

Disney darling Selena Gomez arrived in Italy for the Venice Film Festival to promote her new film Spring Breakers, but this biker-inspired ensemble is a bit questionable.

We prefer Justin Bieber's 20-year-old ladylove in something a bit girlier. The peace symbol cut-out on the back of her shirt is cute. But the white bra ... not cute.

Let's hope her red carpet look will be a complete 180!

The Biggest Loser is set to return in January, and after taking a brief hiatus to expand her family, Jillian Michaels will reprise her role as one of the tough trainers on the upcoming season.

The show is following a slightly different format this time around, marking the first time youths between the ages of 13 and 17 will participate as contestants on the series. Waging a war against the national increase in childhood obesity, the teens will join teams to compete in the fitness challenge. The youngsters will not be subject to elimination or weekly weigh-ins, however, as producers are being "incredibly sensitive" to safeguarding them.

"It's brave, it's bold and I'm sure it's going to be controversial, and we'll do the best we can to handle it in the most positive and effective way possible. It's about getting them on the softball team, not into a size four," Michaels explained.

The goal will be for the kids to focus on their health, not necessarily their weight. Each team will include at least one youngster. In addition to Michaels, trainers Bob Harper and Dolvett Quince will be returning.

Michaels adopted daughter Lukensia earlier this year, and welcomed an infant son with partner Heidi Rhoades mere weeks later. So will motherhood change her tough approach to fitness?

"I am a different person, motherhood changes your DNA. However, being a mom and doing this job are very different aspects of my life and personality. I'm not going to make any promises," she confesses.

We can't wait to tune in and watch the new cast get healthy with the help of Miss Michaels!

Kristen Stewart looks breathtaking in Gucci on the October issue of British Vogue.

Robert Pattinson's former girlfriend doesn't talk about her troubled love life, but she does give her thoughts on having a hard time keeping cool in Hollywood.

"I know if you haven’t thought about how you want to present a very packaged idea of yourself then it can seem like you lack ambition. But, dude, honestly? I can’t. People expect it to be easy because there you are, out there, doing the thing that you want and making lots of money out of it.

But, you know, I’m not that smooth. I can get clumsy around certain people. Like if I were to sit down and think, ‘OK, I’m really famous, how am I going to conduct myself in public?’ I wouldn’t know who that person would be! It would be a lot easier if I could, but I can’t.”

The 22-year-old actress recently admitted to having an affair with married Snow White and the Huntsman director Rupert Sanders. KStew adds: “There is always going to be that seam of people who want things differently to the standardized version. It’s not necessarily a rebellious thing, it’s just who they are."

After more than 15 hours in the air, Paris Hilton looked picture perfect after touching down at LAX from a week-long trip to Shanghai, China.

Wearing a sexy black leather jacket and asymmetrical blue dress, the gorgeous blonde heiress was happy to sign autographs for a crowd of her adoring fans.

Welcome back to the States, P!

Over the weekend, Jeremy Renner and Rachel Weisz turned heads on the red carpet at the premiere of their film The Bourne Legacy during the 2012 Deauville Film Festival in France!

Jeremy was looking dapper in a Lanvin tux, Dior white shirt and bow tie, and Christian Louboutin shoes while Rachel was equally stunning in a Nina Ricci dress, Bulgari jewelry, and Guiseppe Zanotti shoes.

Before the premiere, the co-stars attended a photo call to promote the spy thriller that picks up where the previous three movies left off, which is in theaters now. These two make a great couple on the carpet!
