Rihanna: Girls?? Night at Greystone

Rounding out her weekend with some crazy cool fun, Rihanna showed up at Greystone nightclub in Beverly Hills last night (April 7).

The We Found Love songstress donned a snazzy black, red, and white getup as she strolled out of the popular establishment with a few gal pals.

And it sounds like there may be more trouble in paradise for Ri-Ri and her tumultuous boyfriend Chris Brown, as hes been rumored to be running around on her.

An insider told press that the Dont Wake Me Up singer met a blonde waitress in New York City last month and hes totally smitten.

They hit it off and headed out together. They also spent Easter Sunday together, claimed the snitch.
