Diddy is struggling to watch ex-girlfriend Cassie Ventura move on publicly while also dealing with the death of ex-wife Kim Porter.

The 32-year-old recently posted a photo of herself kissing her new beau, personal trainer Alex Fine, on Instagram. Sources close to Diddy told People Diddy feels the timing is inappropriate, as Ventura knows what he's having a hard time right now.

"If there is anyone who knows how absolutely devastated Diddy has been since Kim's death, it's Cassie. He can't believe she feels the need to post pictures with her new guy. It's like she did it to upset Diddy more," the insider claims.

The source continued, "The whole situation is just ridiculous. There is just no need to post pictures on social media at this point. Diddy is having enough of a hard time."

To make matters worse, Diddy reportedly thinks Ventura cheated on him with Fine. The new couple have apparently known each other for several months – including some time before Diddy and Ventura ended their relationship. The music mogul is certain "there was absolutely overlap."

"Cassie wanted a personal trainer, so Diddy hired Alex for her. Then Cassie and Alex started hooking up before her relationship with Diddy was over," the insider said.

Venture posted a photo with her new boyfriend one day after Diddy shared a picture of her in a bubble bath. He added a heart emoji over the image and tagged his ex-girlfriend, who no longer follows him on social media.
