Ciara has called off her engagement with rapper Future after reports surfaced that he cheated on her. Ciara called off the engagement just three months after the couple welcomed their first child, Future Zahir Wilburn, on 19 May.

"He cheated on her. Game over," a source told Us Weekly of the rapper. "She's devastated. Ciara's focus now is the baby," another source said.

Cheating rumours first surfaced in July when blogger Sandra Rose wrote that Future has been getting too close for comfort with his "wardrobe stylist" Tyrina Lee. Reportedly, Lee was on tour with Future while Ciara was in labour, and Rose said that he spends all his free time and money on Lee.

"She flies 1st class on private jets with Future, and she wears expensive high end bags and shoes, which she posts on her social media for Ciara to see. They don't call Tyrina 'Princess' for nothing," the blogger wrote.

Future proposed to Ciara with a 15-carat diamond ring on the singer's birthday in October 2013, after dating for more than a year. The couple met while working together, and Ciara said in a recent interview that she knew right from the start that Future was "different."

"Our label put us together," she dished to Brides magazine about meeting Future, according to US Weekly. "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."

Reportedly, Ciara was warned by her friends about getting involved with Future, but she did not pay them any attention as she was in love.

"Honestly, she feels like one of the stupidest women in the world," a friend of Ciara's told HollywoodLife. "All of her friends told her he was no good from the jump. They all told her not to trust him, but she was in love and she ignored all her friends who warned her about him."

And now that she has ditched Future, Ciara is also planning to return the stunning engagement ring that he gave her, the source added.

"I think she'd give it back," the source said. "At this point, I don't think she wants anything to do with him. He just didn't cheat on her, he cheated on their little boy. By doing what he did, he basically said, 'F**k you and our Future, Ciara.'"
