Diddy Is Upset Because Cassie Is Sleeping With Trainer Alex Fine

Diddy tried to social media holler at his ex Cassie last week.

She didn't directly respond. At least not publically. Instead, she Instagram posted a photo of her making out with her new fellow, personal trainer Alex Fine. It turns out Diddy had hired Fine to train Cassie last year and is now feeling betrayed that the two are together.

Diddy believes Cassie and Fine were hooking up before he and Cassie split. Cassie's camp denies that, telling TMZ she only started sleeping with the staff when her relationship with Puff had ended.

Anyway, they seem happy and in good shape.
