Ciara and Future are no longer an item. Rumors first sparked earlier this month about a breakup, after the singer was spotted in Ibiza without her engagement ring. Future proposed to Ciara on her birthday in October 2013, but now the engagement is off.

“He cheated on her. Game over,” a source tells Us Weekly. “She’s devastated. Ciara’s focus now is the baby.”

The 28-year-old recently gave birth to their first child together, Future Jr., and posed for Bride magazine last month, while explaining how she knew Future was the one for her. “I knew right away that he was different. Now he's my best friend in the world, my partner," Ciara said at the time. She and Future met through her label, and they began dating in 2012.

In January, Ciara confirmed on "The View" that she was pregnant with her first child after her fashion choices sparked months of speculation. The R&B singer shared many photos on her Instagram page, primarily showing herself in baggy clothes that hid her stomach, prompting fans to figure she was hiding a baby bump.

After she gave birth, Ciara’s then-fiancé told Us Weekly, “She'll be a great mom. She's working at it every day, and over time, I think she'll be the best.” Speaking of his newborn son, Future added: “I want him to be better than me. I would encourage him in anything he wants to do. I want to be behind him, of course.” He was also asked about diaper duty, saying: “You have to say you did it. I'll make sure I change a few diapers -- a hands-on dad.”
