Uh-Oh! Is Rihanna hooking up with Chris Brown?

A report has claimed that Rihanna is hooking up with her ex, Chris Brown.

Yes, the same Chris Brown who brutally assaulted her a few years back.

It is alleged that the pair are seeing each other casually.

“She comes to see him anytime she’s in L.A. They can’t get enough of each other. I don’t see it ending well,” a source told US Weekly.

“Rihanna loves to live dangerously, and talking to and hooking up with Chris is all part of that.”

Chris rep is said to have rubbished the claim, but says they are friends now.
