Rihanna and buddy Rob Kardashian kicked back in LA this past weekend to celebrate a close friend's birthday, after they both sat down for interviews with Oprah.
Earlier in the day ROb and RiRi, along with a group of friends, hit up Racer's Edge Indoor Karting in Burbank, CA to celebrate mutual friend Capricorn's birthday. The bunch seemed to have enjoyed their racing.
The group ended the night by club hopping of course. First hitting up LA hotspot Playhouse then heading over to the grand opening of the Pink Dolphin, a new LA club. Although, Chris Brown reportedly partied across the room at the new hotspot, Rihanna carried on separately with her party.
