Has Ciara called off her engagement to Future just three months after having a baby?

The pair have yet to comment, but multiple sources told Us Weekly they're calling it quits. "He cheated on her. Game over," an insider said about the rapper.

Ciara, 28, and Future, 30, got engaged in October when Future proposed with a 15-carat ring. At the time Ciara tweeted: "If I'm Dreaming I Don't Want To Wake Up..Aaaaaahhh!!!"

They welcomed their son, Future Zahir Wilburn, in May.

Shortly before giving birth, Ciara, opened up about her pregnancy, telling CBS News, "I'm so excited. Honestly, these are the happiest years of my life...I feel like now I'm really becoming a woman with everything that's happening...Getting prepared for something like this is so much fun. I feel like a little kid waiting on Christmas for the day I get to meet my baby. It's so beautiful and it's something I've always looked forward to."

Future has three children from previous relationships.
