Celebrity ex present: Rihanna

Celebrity ex present - Chris Brown

It has been three years since the infamous incident between Rihanna and ex-boyfriend Chris Brown at the Grammys in 2009 - after the show, he assaulted her and has since admitted to his crime. He was also there this year, performing and picking up a gong for his album F.A.M.E. He and Rihanna steered clear of each other for most of the event though. A run-in between the ex-couple could have been very awkward!
