Pro tip: Don’t insult Britney Spears during one of her concerts, or she will call you out on stage in front of everyone.
During a concert Wednesday night, a fan allegedly called Spears a “fat bitch” when she turned around to start a song. It turns out the 33-year-old heard him, and dropped the f-bomb right back at him.
“Fucking asshole.”
You can’t hear the fan’s comment on the video, but you can definitely hear what Spears said.
