Britney Spears is not putting up with any fat shaming from concert hecklers.

Let's set the scene for you: Wednesday night, April 15. Sin City. Britney is ready to slay yet another performance of her Vegas residency, when some dude in the audience calls her a "fat bitch." Even though this guy's disembodied voice seems far enough away from the stage that Britney wouldn't have picked up on it, she immediately mutters — into the mic, no less — "f---ing a--holes!" The heckler is then heard saying, "I think she heard me." (You can watch the whole exchange in the video above.)

First of all, Britney is Fierceney and completely shut that dude the heck down. Second of all, WTF is up with "fans" who think it's 100 percent okay to say nasty, mean-spirited and derogatory things to artists as if they won't hear them? We see it on Twitter on the daily, and it is flat out wrong.

Britney and her epic comeback join the ranks of fellow pop superstars Kelly Clarkson and Demi Lovato, who have also famously silenced fat-shaming haters with some seriously kickass responses. Werk it, ladies. You need absolutely none of that cruelty and hate in your lives.

Britney Army, watch Britney Spears react to the fat-shaming heckler in the video above. What do you think of her response?
