The Umbrella singer was not the only one to be taken aback when Jay-Z and Beyoncé tied the knot at the last minute.
At an event raising money for the Believe Foundation, organised by the record company Island Def Jam, Rihanna exclaimed, "I didn’t know! No one knew!"
Other artists at the event included Chris Brown whom many believe is dating Rihanna. Rihanna spoke about the rapper whom she insists is still just a friend. "Chris really enjoyed it."
