Sources say Jigga man is not feeling RiRi and Breezy's recent reconciliation...

Actually, we hear he's quite "disgusted" by it, especially after now having a daughter of his own.

Rihanna and Chris Brown teamed up on not one by TWO songs.... one of them being Rihanna's "Birthday Cake" remix...where both Chris and RiRi get very raunchy!

Allegedly one insider said,
“Jay doesn’t understand how a man could ever lay hands on a woman; it just goes against who he is and about. Chris is absolutely dead to Jay, he wants nothing to do with him ever. Now that Rihanna is hooking up with Chris and recording songs with him, Jay is deeply disappointed in her actions. He can’t fathom why Rihanna is doing the things she is doing.”

“He understands the need for forgiveness, but he is adamant that Rihanna shouldn’t forget what Chris did to her. Jay wonders what kind of message this is sending to Rihanna’s young female fans."

So far these reports are not confirmed, but if you remember Jay and Chris Brown have had their issues in the past...
