Michael Phelps is once again a single man.
The 22-time Olympic medalist swimmer has split from his model girlfriend of nine months Megan Rossee, TMZ reports. Phelps, 27, pulled the plug on their romance when he felt that the relationship wasn't going anywhere, sources tell TMZ.
Phelps first stepped out with Los Angeles-based model Rossee, 25, in August at a London Olympic event, but the couple had officially dated since March 2012.
Though he retired from swimming after his success at the London Games, Phelps isn't going to spend 2013 just hanging around. The newly single athlete will appear on the Golf Channel's Haney Project in February.
"I have traveled the world through swimming, but really haven’t had an opportunity to experience the world through my travels," Phelps -- whose golf game will get some pointers from host Hank Haney -- has said. "As I enter this next chapter of my life, I think I will be able to shift my competitiveness to anything I put my mind to and golf is one of the things I want to focus on."
