A$AP Rocky has just been added to Rihanna’s North American Tour, Diamonds. It looks like he’s warming up to open for the “good girl gone bad” by performing his remix to ‘Cockiness’ on the cross country tour that he’s finishing up. At his most recent show in LA Rocky performed the song and the crowd went wild, literally- he got them to form a mosh pit! Rihanna was backstage at the show and said that she loved the crowd’s vibe and that A$AP is perfect for her tour. A$AP is set to release his new album early next year, just in time for the start of the Diamonds run. Click below to watch the LA performance and some of the backstage footage of Rihanna.
