Britney Spears Calls Out Heckler At Las Vegas Show

The Toxic hitmaker was performing her Piece of Me show at the Planet Hollywood resort in Sin City when a member of the audience began jeering at the star, branding her a "fat b**ch".

Spears made an exclamation before turning back to continue with her next song and yelling "f**king a**holes" at the heckler.

Video footage of the incident has since surfaced online.
