Britney Spears is being sued for battery and negligence by a dancer who claims the pop star smacked her in the face and broke her nose on the set of "Work Bitch." Hit me baby one more time!

Dawn Noel was on the set of the shoot on August 19, 2013 in Woodland Hills, California, and she claims that when Spears arrived, she was "in a disheveled and confused state." She added in court docs, "although the choreography involving Spears was fairly basic, she was having difficulty learning the moves, performing dance steps and following simple directions."

Apparently after 30 minutes of rehearsing, Spears "twirled in an unbalanced and reckless manner, arms extended out to her sides and forcefully backhanded" Noel directly in the face. The breaking of Noel's noise made "a cracking sound" that was heard by other dancers, but she didn't go see a doctor until later in the day.

So what's the problem? Noel claims Spears' reps and Reign Deer Entertainment company agreed to pay her medical expenses, but later backed out. She is suing for serious physical and emotional damages including disfigurement to her nose as well as severe emotional distress and anxiety, and she's demanding a jury trial.
