Rihanna Goes to Wilmer Valderrama's Karaoke Night

E! reports Rihanna was spotted partying sans Chris Brown for the second time this week. On Wednesday night she headed over to Hollywood hotspot, Geisha House, where cutie Wilmer Valderrama hosts weekly karaoke nights.  Rihanna arrived with a group of girlfriends and sat in a corner booth, where she enjoyed the music but didn’t get up to perform. “She was not dancing but was really friendly, and smiling," a source told E! "She looked so pretty.”

And of course, Valderrama, ever the gentleman, sent over a bottle of champagne for the singer to toast.  Well, cheers Rih Rih.  We’re rooting for ya!
