Adele glances at Chris Brown when he fails to stand for Frank Ocean at the Grammys
Ocean and Brown have a difficult relationship following their recent brawl outside a recording studio, in which Brown or a member of his entourage reportedly described Ocean with a homophobic slur. However, Ocean has decided not to press charges.
Meanwhile, Brown attended the Grammy Awards with Rihanna - four years after the pair missed the ceremony because Brown had physically assaulted the 'Umbrella' singer.
