With her bulging biceps and flat as a board stomach, Cameron Diaz emerged from the waters off South Beach in a bright yellow bikini this weekend.

Princess Fiona is yoked!

Arnold Schwarzenegger and Maria Shriver put aside their divorce differences yesterday when Maria met Arnold and the fam out shopping in Beverly Hills on Arnold's birthday.

Amy Winehouse was preparing to adopt a 10-year-old girl from the island of St. Lucia, the girl and her grandmother told a British paper today.

The girl -- Dannika Augustine (seen above with Amy) -- says she met the singer during one of Amy's visits to the island over the past few years. She says she was living in poverty with her single mom when Amy took an interest in her.

Dannika tells The Sunday Mirror, "Amy was already my mother. I would call her mum and she would call me her daughter. She took care of me and we had fun together. I loved her and she loved me ... She was the most amazing person and I was looking forward to living with her here or in London. I cannot believe she is gone. This is the worst thing that ever happened to me."

Dannika's grandmother Marjorie says she spoke to Amy a few weeks ago and that Amy planned to return to St. Lucia next month. She told the paper, "Amy wanted to have a child so bad. If she had not died, there is no doubt she would be here in St Lucia completing the adoption process. There is no way she would have done what she did to herself if Dannika was with her."

Arnold Schwarzenegger celebrated his 64th birthday today by going bicycling with some friends along Venice Beach.

The former governor of California loves a good ride.

Later ... Arnold hit up his favorite lunch spot, Cafe Roma, where the paps sung him "Happy Birthday."

Lindsay Lohan went out again in Malibu last night with pals Paris and Nicky Hilton and she just couldn't stand it -- no, really ... she fell down.

Lindsay blamed her little trip on the paps, posting this on her Twitter page:

Kristin Cavallari threw on a small black dress and hit up a hotspot last night she KNEW she'd get photographed at ... STK in Hollywood.

Like Hollywood's version of the Camp David Accords, Paris and Nicky Hilton reunited with their old long lost pal Lindsay Lohan at a restaurant in the Palisades last night.

It appears Paris and Linds are super serious about rekindling their friendship -- they also partied together last weekend at Hilton's Malibu beach pad.

But this time, they made sure everyone could SEE the reunion ... and HUGGED IT OUT at the end of the night -- right in front of the cameras.

UPDATE: We're told the reunion wasn't planned -- the two just happened to bump into each other while going to dinner with different people.

Mila Kunis now has something in common with Michael Jackson besides at one time having a close relationship with Macaulay Culkin ... they both have a penchant for hanging out on balconies in the same hotel.

On Thursday, the "Friends with Benefits" star was spotted on a Hotel Adlon balcony in Berlin -- which is the same hotel where Michael infamously dangled his son Blanket back in 2002.

Kelly Osbourne and Amy Winehouse's father Mitch gathered at a London club on Thursday to commemorate the late singer's life. Also in attendance were Mark Ronson and Amy's boyfriend Reg Traviss.

The cause of Amy's death has yet to be determined.

Looking tough with his shaved head, Jake Gyllenhaal brought out the big guns to portray a cop on the set of his new flick "End of Watch" in L.A. the other day.

While in Hawaii for his Dad's wedding this weekend, super sexy Jake Gyllenhaal cooled off his ridiculously hot and buff body at the beach in Oahu.

Vanessa Branch -- the chick from the Orbit gum commercials -- showed off a different side (and front ... and back) than we're used to seeing by wearing an exposing sheer dress in NYC on Tuesday.

Fabulous!

It's no Victoria's secret that the 30-year-old is smokin' hot.
