Jay-Z’s got 99 problems and Chris Brown is definitely one of them… also Blue Ivy’s dirty diapers, but that’s another story.

The “N***** In Paris” rapper is apparently furious that Chris and Rihanna are supposedly back together!

Rihanna has been Jay-Z’s protégé ever since he brought her into the industry years ago and now he is upset that she has is making such bad decisions.

As we all know, Brown was convicted for beating up Rihanna back in 2009 and obviously Jay is still not over the event.

Remember when Brown and Rihanna were spotted at Jay-Z’s concert earlier this month at the Barclays Center in Brooklyn?

Well Jay took that opportunity to tell Chris what’s what, warning him to keep his fists to himself!

“Jay-Z told Rihanna that if Chris is truly making her happy then to go for it,” a source reveals. “He invited them as a couple to his concert in New York and backstage he called Chris to one side and told him if he hurts Rihanna, whether emotionally or physically, it’s over for him. He’ll ensure it will result in the end of his career.”

Wow…

You go Jay-Z!
