Rihanna sent out this shot of her hot GQ cover to Twitter followers, showing off her sexy December issue cover shot.

The star, who is pantless for this photo, goes topless in another shot for the mag spread.

As part of the story, writer Jay Bulger went clubbing with Rihanna, and guess who happened to be at the club? Chris Brown. Here’s what happened, according to Bulger:

"Chris Brown brashly stands on top of his bench in the neighboring booth. He and Rihanna start tossing flirtatious glances like kids passing notes in middle-school math class.

The smirks and the playfulness continue until they’re dancing with each other from afar.

Then, out of mock frustration, Brown climbs over the top of the booth. A mischievous tingle of controversy vibrates through the club.

There, in the middle of all the craziness: Rihanna stares straight at me and passes me a spliff.

She turns her green-hazel Bambi gaze back to Brown and begins to sway those famous hips from side to side.

It’s 2 a.m. She looks like she’s just getting started."
