Paparazzi Photo

Katy Perry was all smiles on Thursday, spotted on the Santa Barbara set of a photo shoot for Adidas.

Perry's now sporting a new blue hairdo, but she was sans wedding ring.

Russell Brand was spotted Friday for the first time since the divorce news broke, arriving at LAX with a throng of paparazzi waiting for him.

We're told the couple is on good terms, despite the divorce.

Paris Jackson really is a chip off the old King of Pop.

In the middle of playing high school softball the 13-year-old outfielder broke out one of her late dad Michael Jackson's famous dance steps.

Rocking some interesting blue hair, Katy Perry was spotted out in public on Thursday for the first time since splitting with estranged husband Russell Brand two weeks ago.

The 27-year-old "California Gurl" was all smiles as she posed with a fan while on the set of an Adidas commercial she is filming in Santa Barbara.

As TMZ previously reported, Katy will continue living in the former couple's $6.5 million Hollywood Hills home and Russell will move out.

While Russell filed for divorce after only 14 months of marriage, he and Katy are said to still be on reasonably good terms.

With a big smile on her face, "Real Housewives of Beverly Hills" star Kim Richards hit up Mr. Chow last night ... her first public outing since checking out of rehab earlier this month.

The 47-year-old went to the Beverly Hills celebrity hot spot with her big sister Kathy Hilton.

In December, Kim entered rehab for treatment of alcohol abuse and other "serious issues."

Family members have said Kim is doing "really well" since completing the 30-day program and are optimistic she'll stay on track.

The awards aren't until Sunday, but Playboy's Miss August 2010 Francesca Frigo showed off her gorgeous golden globes in a hot pink string bikini in Miami on Tuesday.

Like a good auntie, Kelly Rowland went shopping for a gift for Beyonce and Jay-Z's baby girl Blue Ivy Carter in NYC on Monday.

The former Destiny's Child member hit up the Lucky Wang baby boutique and picked up a green Bob Marley onesie.

Fresh from vacationing with George Clooney, Stacy Keibler and Cindy Crawford in Mexico, Alex Rodriguez and his new girlfriend/wrestling diva Torrie Wilson continued soaking up the sun and showing off their lean, ripped physiques at his house in Miami this weekend.

Gym. Tan. Lovers.

And if that wasn't convincing enough -- here's a pic of the new couple getting nibbly in A-Rod's pool.

Eddie Cibrian enjoyed a bootyful weekend in Hawaii watching his wife LeAnn Rimes play bocce ball in an itty bitty thong bikini.

Elin Nordegren is SO rich -- she's basically building a replica of the multimillion dollar estate she knocked down.

TMZ has obtained renderings Elin submitted to the Palm Beach County Dept. of Planning, Zoning & Building. The exterior elevation drawing is verrrry similar to the house that was on the $12 million property before Elin razed it. Both are traditional/colonial homes with a very similar shape. The drawing looks similar to the 9,000 square foot house that was demolished.

Elin's builder told PEOPLE the house Elin 86'd was 90 years old, didn't meet code provisions to withstand hurricanes, and was infested with termites.

Of course, the house Elin builds will be brand spanking new. The supporting documents describe the house in detail.

-- 9 bedrooms
-- 2 large living rooms
-- huge formal dining room
-- 2 kitchens
-- large pool
-- GROTTO!!!
-- pool cabana with HUGE living room
-- 2 jacuzzis
-- detached guest house with 3 bedrooms
-- 3 guest bungalows
-- wine cellar
-- ginormous master wing with crazy big walk in closet
-- basement that runs the entire length of the house

There's 120 feet of retaining walls, and they are bringing in 4100 cubic yards of soil -- which is an enormous amount.

County officials have sent the architect back to the drawing board for some changes before the plans will be approved.

For singer Craig David, R&B stands for ripped and buff.

The ridiculously yoked 30-year-old showed off his flawless body during a shirtless run in Miami this weekend.

Even if you don't know any of his music, there's no denying he has an amazing body of work.

Proving they are the happiest separated couple in Hollywood, David Arquette celebrated his first full year of sobriety by eating dinner with Courteney Cox at Mr. Chow in Beverly Hills last night.

Arquette had checked himself into treatment on January 1, 2011 to deal with "alcohol and other issues."

As for the marriage ... the couple separated back in October 2010 ... but never actually filed for divorce.

Dear Aida Yespica,

You lose.

Love,

Just because she's very very pregnant with a bulging baby bump doesn't mean Jessica Simpson can't show off her muscular mom legs in sky high stiletto heels.

The 31-year-old mother-to-be flashed her growing belly and long stems in a printed mini-dress and a ridiculously tall pair of black stripper pumps while leaving a medical building in Beverly Hills on Thursday. Jess has killer maternal fashion instincts.

The singer/actress/style maven and her NFL fiancé Eric Johnson are expecting their first little rug rat sometime in the spring.

The moving pods were out at Katy Perry and Russell Brand's home in the Hollywood Hills Wednesday ... which begs the question ... who gets to stay in the house??

Katy and Russell purchased the $6.5 million, 3 acre, Sunset Strip-area estate back in June ... but just last week, the British funnyman filed for divorce ... leaving the future of the home in limbo.

Not a great time to sell real estate in L.A. ... and if they decide they want to unload the place quick, it might mean a great deal for a potential buyer.

Fashionista Olivia Palermo became famous on "The City," but it was the hills of the buck ass naked woman behind her that got all the attention in this pic taken on a nude beach in St. Barts Thursday.

Looking like Marky Mark wannabes, 17-year-old Justin Bieber and his dad 37-year-old Jeremy showed off their smooth shirtless chests on the beach in L.A. on Wednesday.

There's nothing like quality topless family bonding.
