LONDON -

The newly retired 22-time Olympic medalist Michael Phelps is apparently off the market.

Phelps has reportedly been dating model Megan Rossee for the past five or six months. Rossee is a 25-year-old model and resident of Los Angeles.

On Monday night, Phelps made his first official appearance with his flame on the red carpet at an event hosted by Speedo in London.

Her Instagram account has included many candid shots of Phelps and also a picture of herself pushing a baby stroller with the caption: "Maaaaaybe in 5-10 years."

A candid photo of Michael Phelps, girlfriend and medals in hand, shows him celebrating in London and beaming for the camera.

"Yay Michael" Megan’s caption read.
