The Gossip Madam: Pitch Perfect actress Rebel Wilson strips on stage at the MTV VMAs...and twerks with Nicki Minaj

MTV said they had a 30 second delay in case their controversial VMAs host Miley Cyrus gets up to some of her old tricks on Sunday night's show. But Australian actress Rebel Wilson, 35, caused an uproar when she striped out of a police costume and twerked with Nicki Minaj, 32.

'I really hate police strippers,' she shouted as she took to the stage at the Microsoft Theater in Los Angeles. She then whipped off her outfit to stand before the VIP crowd in just a T-shirt that read 'f*** tha stripper police (sic)' across it and her bare legs. 'That's what I'm talking about. They [police strippers] come to your house, you think you're getting arrested and you're just getting a lap dance,' she joked. 'I hired a police stripper for my grandma's 80th and he wouldn't even feel her up, so I paid an extra $100 for her to get an erotic back massage but I only lasted for one song, I hate this injustice,' she added.
