Michael Phelps and his girlfriend Megan Rossee have apparently broken up.
The Olympic swimming sensation, who has a record 22 medals and retired after the Summer 2012 Olympic Games, ended his relationship with Rossee, a model, because it wasn’t going anywhere and he wanted to pursue other options, according to TMZ.com.
“Things happen for a reason. #notme,” Phelps, 27, wrote on Twitter Monday.
