One of Britney Spears' former music video co-stars has threatened to file a lawsuit against the singer for injuries she sustained on the set.
Dawn Noel is planning to file a lawsuit, according to TMZ.com, claiming Spears accidentally slapped her as they were rehearsing a dance sequence for the 'Work Bitch' promo in August.
Noel claims the unbalanced pop star smacked her in the face with such force that everyone in the room heard a cracking sound.
The dancer reveals the slap left her in excruciating pain, but Britney simply apologised and then continued the rehearsal.
Noel claims a doctor later told her she had sustained a nasal bone fracture and needed surgery.
She claims Britney's handlers promised to pay her medical bills, but she's still waiting for compensation.
TMZ.com reports Noel's lawyer Sark Ohanian will file a lawsuit on Monday.
