The Olympic sensation, who won his 22nd career medal in the 2012 Olympic Games, has notoriously been quiet about his love life, but he went public with his relationship on the red carpet on Monday.
Rossee, a 25-year-old blond beauty, hasn't been shy about sharing their relationship on Instagram, posting a cuddly picture of herself with Phelps on Sunday with the caption “Yay Michael.”
Rossee has reportedly been quietly seeing the swimming superstar for months, according to Hollyscoop.
“She and Phelps began dating in January (2012) and things started to heat up just prior to the Olympics,” a source told the gosisp site.
But Rossee doesn’t seem to have been trying to keep the relationship a secret - she’s tweeted quite a few candid shots of Phelps over the last month, and posted updates from the Olympic Trials as well which she reportedly accompanied Phelps to.
The 5’9” stunner describes herself on her website as a Los Angeles-based model and actress. “I am super easy going and pretty much down for any type of project (that doesn’t involve nudity),” she wrote on her Model Mayhem profile. “I love what I do and hope to further my career as a model as well as a performer.”
But Rossee hinted her recent lifestyle of accompanying her athlete boyfriend around the world was proving tough to balance with her own career.
“This summer has turned out to be very busy for me, so I am no longer accepting [modeling opportunities] unless hair/makeup or wardrobe are provided, or if the project is something my portfolio is lacking,” she wrote.
Despite his jam-packed schedule, Phelps reportedly got serious about Rossee quickly after they first got involved.
“Michael knew that he had to leave for the Olympics and not wanting to give up on their relationship, he flew Megan out to the trials in Omaha and then to London for the Games,” Hollyscoop quoted the source as saying.
As for Rossee, while she had no hesitation in showing off her affection for her man, she seems in no rush to take it further just yet.
Posting a picture of herself pushing a baby carriage on Instagram in June. “Haha,” she joked. “Maaaybe 5-10 years down the road.”
