An audience member at a Britney Spears concert had the nerve to yell out a low blow during a recent show in Las Vegas.

It's the new trend that makes you an instant internet star! Do something dramatic at a concert.

According to YouTube user Zafer Sari, Britney stood up for herself during a recent show when someone stood up and apparently yelled out "Fat B****", basically fat-shaming her while on stage.

Britney's southern roots took over with the response 'what a "F***ing A***hole.' She obviously had enough of this person to scream that out on the mic.  You can hear it clearly in the video above.

Go Brit!!  Did he know that's "Britney B***H?"
