Video footage has emerged of Britney Spears calling a heckler a "fucking asshole" during her Las Vegas show last night (15 April).
The singer was performing at Planet Hollywood as part of her Piece of Me Las Vegas residency when, with her back to the crowd as she kicked off 'Till The World Ends', she said loudly, "Fucking asshole."
It's not entirely clear who she was referring to, but numerous reports claim that a member of the audience called her a "fat bitch". If that is the case, then her explicit response was entirely justified.
