Swimming superstar Michael Phelps won six medals in London, making him the most decorated Olympian of all time. But he also has other reasons to celebrate.He was identified by several media sites as aspiring model Megan Rossee, 25, from Los Angeles.

The 5-foot-9 Rossee, 25, posted a photo to her Instagram account Sunday of her and the Olympian with their arms intertwined, and Phelps holding his six medals from London.

"Yay Michael," she tweeted alongside the photo.

The Los Angeles-based model hasn't tried to hide her relationship with Phelps. She tweeted at the swimmer Aug. 2, saying, "good luck tonight bear ‘@MichaelPhelps: Last prelim swim complete... 2 big ones tonight... Nap time now...'"

Rossee also accompanied Phelps, 27, to the Olympic Trials in Omaha June 28.

Phelps wrapped his Olympic career Saturday, taking four gold and two silver medals home from London.

Michael Phelps won the men's 200m individual medley at London 2010 from his USA team-mate Ryan Lochte. For the second time this Olympics, Michael Phelps and Ryan Lochte were neck-and-neck Thursday in London - in their final event together of the Summer.

After losing to Lochte in the 400 individual medley last Saturday, Phelps, 27, managed to out-swim his friend and teammate in Thursday's 200-meter individual medley by only .63 seconds.

Phelps's gold medal-winning swim - clocking in at 1:54:27 - brought his total number of medals to 20 (16 gold), while Lochte's silver upped his own count to 11. Great going Guys!

Phelps has, in all likelihood, two competitive races left. On Friday night he will go in the 100m butterfly, against one old rival in Milorad Cavic and one young one in Le Clos.

Lochte, who turns 28 Friday, is done for the Games. His other Thursday night final - the 200 backstroke, traditionally his best event - nabbed him a bronze medal, while teammate Tyler Clary took home the gold."Sometimes you have it, sometimes you don't," says Lochte. "But overall, I can't be too disappointed. I am coming home to my country with five Olympic medals."

The 25-year-old American swimmer and Olympic champion, Michael Phelps and American model, socialite, and reality television personality, Brittny, 28, are "really cute together," a source close to her told People, adding, "It's just started."

Gastineau and Phelps sparked relationship rumors when they were spotted together getting cozy at the Mondrain Hotel in Los Angeles Friday night and were seen again shopping the next day at The Grove.

Although she won't confirm or deny reports that she's dating Michael Phelps, socialite and former reality TV star Brittny Gastineau has confessed that she finds the Olympic gold medal winner attractive. "She thinks he's a really sweet guy," the source said. "She understands his athletic background since her dad was an athlete." Brittny's dad, Mark, played for the New York Jets!
