Cassie may have jump-started the new year with a new romance, but not without a word or two on the matter from her ex, Diddy

According to a new report from TMZ, the rap mogul allegedly felt “betrayed” after the singer revealed she was dating personal trainer Alex Fine.  Why?  Because Diddy is the one who hired Fine to train his ex over the past year.

This piece of news has sparked a bevy of rumors that Cassie may have been unfaithful during the course of her 10-year relationship with Diddy. 

Cassie’s camp claims she didn’t start dating Fine until after her split with the Bad Boy CEO, but according to TMZ, Diddy is supposedly convinced there’s some sort of overlap.

As previously reported, Cassie not-so-subtly announced her relationship with Fine with an Instagram photo of the two of them kissing.
