A concertgoer learned the hard way that you do not want a piece of Britney Spears! While wearing a figure hugging bodysuit and performing her hit song “Till The World Ends” a heckler hurled unkind comments at the pop star calling her a “fat b*tch“. The loud insult was heard by the performer and she responded into her microphone, “F**king A**holes”, and continued her performance like a seasoned pro; never missing a beat!

After a brief hiatus, the 33 year old mother of two, just returned to the stage at Las Vegas’ Planet Hollywood Resort and Casino to continue her Piece of Me residency. According to Us Weekly the “Work B*tch” singer, who has shows scheduled through September, has yet to comment on the incident.

Spears is not the first star to respond to fat shaming comments, recently singers Kelly Clarkson and Pink have also responded to critics who have made nasty comments about their weight.
