Now that his Olympics run is over, Michael Phelps is making the most of the time he has left in London-town -- with his new girlfriend, Megan Rossee, by his side.

The gold medal-winning athlete, 27, and his model love of five months, walked the red carpet together during a Speedo event in London Monday night. See more photos of the new couple in London.

Though they proudly posed for pics, Phelps refused to answer when reporters asked him about his current relationship status.

Earlier Monday, E! confirmed that the athlete has in fact been dating the 25-year-old Los Angeles-based model for about five months.

Rossee had been showing her support for the swim champ as he finished out his third and last Olympics in London over the past two weeks.

"Good luck tonight bear," the 5-foot-9 stunner, who has walked in Michael Kors, Betsey Johnson and other designers' runway shows, tweeted on August 2 in response to Phelps' own tweet, "Last prelim swim complete... 2 big ones tonight..."
