It’s over for Ciara and Future.

Three months after welcoming their son, Future Zahir Wilburn, the “I’m Out” singer, 28, has split from her rapper fiancé, Us Weekly reports.

“He cheated on her. Game over,” a source told the magazine.

“She’s devastated. Ciara’s focus now is the baby,” another source said.

Future (real name Nayvadius Cash), 30, popped the question in October.

In July, Ciara graced the cover of Brides magazine.

“Our label put us together. I went into the studio strictly to work, but he was very calm and sweet, a gentleman … I knew right away that he was different. Now he’s my best friend in the world, my partner,” she said.

A rep for Future did not immediately return a request for comment.
