Diddy seems to think that Cassie was sleeping with her trainer, but she claims these allegations are completely false.

The NY rapper may be asking his former trainer, Alex Fine, for a refund because he may have slept with Cassie while the she and the rapper were still together.

Cassie however, says that she did not sleep with him while Diddy was paying for her training. He’s got the timeline all wrong!

According to TMZ, the couple split several months ago after being together for 10 years!

Sources claim that Cassie and Alex hooked up before her split with Puff, but it IS a bit difficult to tell if she cheated.

One thing is for sure, she moved on kind of quick!
