Is there something going on behind the scenes with Rihanna and Chris Brown? Sources indicate that might be the case. And with their Twitter dalliance continuing, hey, anything's possible.

In the new Us Weekly, a source says the pair "meet up casually." "She comes to see him anytime she's in LA," the source adds.

A unnamed music industry source corroborated that story.

"They can't get enough of each other," the source says. "I don't see it ending well."

"Rihanna loves to live dangerously, and talking to and hooking up with Chris is all part of that," said a person close to Rihanna.

February 8th will mark the three-year anniversary of the fateful night when Chris Brown and Rihanna had their infamous Grammy night domestic violence dispute. Brown currently has a girlfriend, model Karrueche Tran.

"He and Rihanna are just friends," Brown's rep told Us Weekly. "He's not cheating."
