February 8 marks the three-year anniversary of Chris Brown's infamous assault of then-girlfriend Rihanna.

And it turns out that the exes — forcibly separated after the beating by court order — could very well be spending that "anniversary" together. As multiple sources confirm in the new Us Weekly, Rihanna, 23, and Brown, 22, have secretly been hooking up for nearly a year.

The edgy, platinum-selling "We Found Love" singer and Brown "meet up very casually," a Brown confidante says. "She comes to see him anytime she's in L.A."

Explains a music industry source: "They can't get enough of each other. 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," adds a Rihanna insider.

The clandestine relationship isn't just complicated because of the couple's violent past; the "Forever" crooner also has a girlfriend, aspiring model Karrueche Tran.

"He and Rihanna are just friends," Brown's rep tells Us. "He's not cheating." Rihanna's rep had no comment.

For much more on this shocking reunion — how the secrecy makes "the hookups even hotter" and whether they'll ever go public — pick up the new Us Weekly, on stands Friday.
