Rihanna and buddy Rob Kardashian kicked back in LA this weekend to celebrate a close friend's birthday, after they both recently sat down for interviews with Oprah.
Earlier in the day Rob and Rih, along with a group of friends, hit up Racer's Edge Indoor Karting in Burbank, CA to celebrate mutual friend Capricorn’s B-day. The bunch seemed to have enjoyed their racing, as all were pictured deeply concentrating on becoming first to hit the goal line.
The group ended the night by club hopping of course. They hit up L.A hot spot Playhouse, which hosted the grand opening party for lifestyle brand Pink Dolphin's new flagship store. Chris Brown partied across the room at the event, but Rih carried on separately with her crew.
Rob Kardashian's girlfriend is Rihanna's fellow Roc Nation signee Rita Ora. The two singers linked up and snapped some pictures together at the The Throne's London show back in May.
