Rihanna and Chris Brown, starting their exciting night on the town with dinner at Giorgio Baldi in Santa Monica. Then, the two popped into the Hideout, a small bar next door. “They came in with their bodyguard and watched people getting up to sing karaoke,” says an onlooker. “They were laughing hysterically –not at everyone, but they just thought it was so cute and funny.” Alas, neither pop star took turns on the mic. After getting their fill, the two left, holding hands on the way out the door.
