(LOS ANGELES) — Swimming superstar Michael Phelps won six medals in London, making him the most decorated Olympian of all time. But that might not be the only thing he’s celebrating.
The 22-time Olympic medalist is dating aspiring model and blond beauty Megan Rossee, according to Hollyscoop.com.
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.
“So happy for @MichaelPhelps so awesome to watch u finally 🙂 Congrats and yayyy,” she tweeted from the competition.
A source told Hollyscoop, “She and Phelps began dating in January  and things started to heat up just prior to the Olympics.”
Rossee works as a cocktail waitress at Blok nightclub in Hollywood, according to Hollyscoop. She has modeling-acting experience in high-fashion print, runway, film and television, according to her website.
“I am super easy going and pretty much down for any type of project (that doesn’t involve nudity),” her Model Mayhem profile says. “I love what I do and hope to further my career as a model as well as a performer.”
Baltimorean Phelps has announced that he is retiring from Olympic competition and would like to travel the world but he might not be alone in his travels.
“He wants her [Rossee] to travel the world with him but she hasn’t made her decision yet to quit,” Hollyscoop reported. “She’s heavily considering it.”
