Yikes! Looks like being a back-up dancer for Britney Spears should be added to the list of hazardous jobs. One of Brit's dancers, Dawn Noel, is suing the pop star for breaking her nose in August 2013.

During rehearsals for one of Britney's music videos, a reportedly "disheveled" Spears did an unbalanced turn, whacking Noel in the face. After a half an hour, the dancer could no longer bear the pain and went to the doctor. She had to have surgery -- and though Britney's people promised to pay for it, months passed and it was ignored... so she's suing!
