Chris Brown is smooth

While Rihanna celebrated her 21st birthday with close friends on Friday, Chris called to wish a happy birthday and attempted a reconciliation. A source says, “He knows he’s very much in the doghouse right now, and is doing everything he can to show her how sorry he is.” Two weeks ago he beat Rihanna leaving her with contusions, bruises and bite marks. To say he’s “in the doghouse” is an understatement. A better analogy would be he’s in the stables at the factory about to be turned into glue.

Still, Brown is doing everything he can to get back in Rihanna’s good graces. He even sent her “a diamond bracelet and necklace and an iPod Touch.” Wow. Really? I don’t see how Rihanna can resist. Sure, Brown made her look like the victim of an impromptu MMA fight and for a few days after, she resembled Satan, but it’s jewelery and an iPod! The world’s two greatest aphrodisiacs.

Joking aside, a source also says that Rihanna wants to be back with Chris, but realizes it’s probably not a good idea because dating him would be like dating Ryu from Street Fighter. He’d always be trying to land that dragon punch.

“Rihanna so wanted Chris with her on her big day, but obviously realizes why they can’t be together right now,” our insider says. “But it’s becoming more and more clear that she can’t be without him.”

The gorgeous songbird had something to celebrate besides her B-day — she’s healing quickly from her recent injuries. “She hasn’t scarred or anything,” our insider reports. “She was in a great mood. She was really celebrating not just her birthday, but life in general.”

If Rihanna ever gets back with Chris, you sort of wonder what else she would do. Play chicken in traffic, swim with sharks without a cage, punch a lion in the balls, anal? The possibilities seem endless.
