Watch Britney Spears Curse at Hecklers in Vegas

Britney Spears is not going to put up with your sh*t!

During Wednesday night’s performance of her Vegas show, someone up front called Britney a “fat bitch” (because that is why you drop a few hundred on tickets to her show?).

Britney appears to have heard it, as she replied with a very appropriate, “Fucking asshole!” then goes into “Till The World Ends.”

She’s not that innocent.
