Not everyone enjoyed Drake's headlining Coachella set last night. As the rapper started "Marvin's Room," Justin Bieber tried to make his way backstage to get a closer view and was denied entrance by security. Even though he had the proper credentials, the backstage area was at capacity and no one was getting in. Bieber's team tried to explain why he needed to get out of the crowd, where he'd inevitable be mobbed by fans, then things escalated. After a staff member approached Bieber to invite him backstage, a security guard came up behind him and placed him in a chokehold. Bieber's security clashed with festival guards and Bieber's camp was eventually kicked out of the festival, according to TMZ. The celebrity news site's sources say that Bieber is considering taking legal action against the security guards. Watch the incident above.
