While Michael Phelps has been celebrating his Olympic wins in the Maldives with his male friends, his girlfriend Megan Rossee stepped out in California wearing a gold bikini that showed off her hot body to the public.

The 25-year-old cocktail waitress stripped down to a two-piece at the Santa Monica beach on Wednesday, Aug.15. TMZ's pictures of the blonde beauty show her getting wet in the water while chatting with friends.

Rossee is an aspiring model who considers herself a 5-foot-9.5-inch All-American girl with "experience in High Fashion Print, Runway, Film and Television," according to her website

Her relationship with Phelps  went public when he invited her to the Olympic trials as well as the London Games to join him in celebrating his historic wins.

The couple was first seen together upon their exit from a London nightclub on Saturday, Aug. 4, at 4 a.m. during the Olympic Games. 

"Michael was desperate for her to see more of the world, so he decided that she should join him in London for the Olympics. Michael is completely besotted with Megan and now that he's retired is even thinking of popping the question," a source told RadarOnline exclusively. "Michael and Megan have been an item since January. He met her in Blok nightclub - and despite advances from Paris Hilton's ex Doug Reinhardt, she chose Michael."

On Aug. 5, Rossee tweeted a picture of herself with Phelps with the caption "@michaelphelps "Yay Michael:)" On the 16th, she posted "@michaelphelps "forgot to say thanks for letting me play with you guys yesterdy." 

RadarOnline also reported that the swimmer is absolutely smitten with Rossee.

"Michael is like a puppy dog around Megan - he's completely in love with her," claimed a source close to the gossip site.

After the Summer Olympics ended Sunday, Aug. 12, it was reported that Phelps took a well-deserved vacation in the Maldives Island. However, it turns out that the trip is currently an only guys venture, since the United States star was pictured relaxing with some of his closest male friends minus his main squeeze Rossee, according to Daily Mail pictures. 

TMZ reported that it's a "relaxing bro getaway."

With 22 medals, Phelps is considered the most decorated Olympian of all time. He holds another record for winning the most gold medals ever, a record-winning 18.
