Rapper, Future is allegedly cheating on Ciara with newcomer R&B singer, Tinashe, MediaTakeOut reports.

MediaTakeOut sources claim that Ciara recently walked in on Future and Tinashe "in a compromising position."

The MTO source adds that Tinashe and Future are more than just an alleged fling.

"Future and Tinashe are actually getting kind of SERIOUS. They started working on music together, but their relationship grew . . and now they're officially SEEING EACH OTHER," says MTO.

This isn't the first time that Future was accused of cheating on Ciara.

Back in August, the couple ended their engagement due to Future's alleged infidelity. At the time, Ciara had just just given birth to the couple's first son together, Future Zahir Wilburn.

Though reports from the Hollywood Life claimed that Ciara felt betrayed by Future, the "Body Party" singer later reconciled with Future for the sake of their son.

"Ciara knows he cheated and she hasn't truly forgiven him for that," said a Hollywood Life source at the time. "But she doesn't want to be selfish to her boy and doesn't really want her boy to grow up without a father."

The source also explained that Ciara admires Future's artistry and personality and wants their son "to be exposed to that side of Future's personality."

It is still unclear whether Ciara will choose to breakup with Future following his alleged cheating with Tinashe.

However, Ciara's recent Instagram photo show no signs of Future in attendance at the singer's birthday festivities.

Ciara is currently in New York celebrating her birthday with her son, her friend Lala, and her family.
