Russell Brand makes fun of Justin Bieber

Ricky may have introduced Bruce Willis as 'Aston Kutcher's dad' at Sunday's award ceremony, but Brand was also busy giving his own controversial routine.

The 35-year-old performed to a small Los Angeles crowd and made jokes about Hiltler and Justin Bieber.

Brand was being filmed for a documentary-film about himself, titled Happiness.

The husband of pop star Katy Perry picked on a Justin Bieber lookalike in the audience, asking him: 'Did you do that haircut to look like Justin Bieber?

'I bet you are getting a lot more sex than you used to. Let's be honest - Justin Bieber, he can't f*** any of them anyway, can he? Having instead of a penis a corn nut.'

Russell's film sees him travelling across the US with a group of marines, visiting a tough prison in Louisiana.

Speaking about the marine instructor, he said: 'Hitler would have loved him - all blond hair, blue eyes and muscles. Hitler would have wanted to shag him, saying, 'Oh my, aren't you a big boy.''

Russ added: 'The more time I spent in a really masculine environment, the more gay I became.

'I kept making excuses to try and leave. I told the producers I would be better at researching porn. But they wouldn't have it.'
