X17online can exclusively report that Rihanna went on a date last Friday - her first since Chris Brown - with the Lakers' Andrew Bynum!

The couple dined at Mastro's Steakhouse in Beverly Hills. When they left together, a witness reports that they looked "very couple-y, sitting real close to each other in the car."

Seems like both Chris and Rihanna have moved on, but at least Rihanna's trading up with a hot NBA player!
