A rehab worker who was fired from the Betty Ford Centre in Los Angeles after an argument with Lindsay Lohan is suing the actress.
Lawyers for Dawn Bradley filed the lawsuit in California accusing the star of assault and battery.
She claims she was seriously injured during an argument with the 25-year-old in December and needs surgery on her wrist.
Steve Honig, a spokesman for Lohan, declined to comment on the case.
Dawn Bradley, who is also known by her married name of Dawn Holland, was fired from Betty Ford Centre after talking about the fight with Lohan on camera with a celebrity news website.
A probation report reveals that Bradley had been trying to give Lindsay Lohan a breathalyzer test after she missed curfew and was with two other girls who admitted drinking that night.
The actress was sent to LA's Betty Ford Centre for three months of treatment after failing a drug screening for cocaine and amphetamines.
