Phelps, 27, reportedly broke up with Rossee, 25, because he felt the relationship wasn't going anywhere.

The couple first stepped out together in August at an event in London during the Summer Olympics. They had been together since March.

Phelps will next appear in the new season of the Golf Channel series The Haney Project.
