“She’s in New York right now for Fashion Week, having fun and leaning on her girlfriends,” a source close to Milian tells PEOPLE, confirming the breakup.
The pair had been dating for almost a year prior to the split.
Rumors of their romance began July last year and Milian eventually confirmed their relationship in May.
“There’s nothing better than that feeling of that new chemistry, when you’re so into someone you really could care less about what anybody else has to think” Milian, 33, told Entertainment Tonight about her relationship with the 32-year-old rapper.
“I feel so inspired by the relationship that I’m in. It’s like that careless, hopeless-romantic love where it’s like, ‘Oh my gosh, I will do anything for you,’ it’s just incredible.”
Milian currently has her own “docu-soap” on E!, Christina Milian Turned Up.
ET was first to report the news. A rep for Milian has not responded to a request for comment.
