R&B star Chris Brown has been banned from participating in interviews by his management team after questions about former girlfriend Rihanna dominated his last album’s promotion. The Kiss Kiss hitmaker’s F.A.M.E. record was released in 2011 but his campaign trail hit trouble when he was questioned on US show Good Morning America about his 2009 assault on his ex. Brown reportedly lost his temper and smashed a window backstage at the TV studio, and now his team is keen to keep him away from interviews as he prepares to release his fifth album, Fortune.
