Leave it to the white boy who's trying to make a big splash in the hip hop world.

Justin Bieber was seen smokingweed during his performance in New Zealand on October 2… and to be honest, it was the same weed that got him arrested for DUI in Miami on January 24, 2014. He was also tested positive for marijuana.

The 'What Do You Mean' singer didn’t end there. He was gulped down a bottle of Hennessey on stage as he performed alongside fellow musician, Rae Sremmurd.
