Troubled child actress Lindsay Lohan is being sued by a former rehab worker, who alleges that the actress assaulted her.

Dawn Bradley claims she was seriously injured during an argument with the 25-year-old in December and needs surgery on her wrist.

After talking about the fight on camera with a celebrity news website, Dawn Bradley was fired from the Betty Ford Centre in Los Angeles.

The actress, best known for appearances in Mean Girls and TV series Ugly Betty, was sent to LA's Betty Ford Centre for three months of treatment after failing a drug screening for cocaine and amphetamines.

A probation report reveals that Bradley had been trying to give Lindsay Lohan a breathalyser test after she missed curfew and was with two other girls who admitted drinking that night.

Steve Honig, a spokesman for Lohan, declined to comment on the case.

This is just one of many brushes with the law, that the 25-year-old actress has faced. She spent 35 days at her apartment for stealing a necklace last January and is now working at a shelter for women and LA's county morgue.

Lohan is also still on probation over a 2007 drink-drive case. And the actress was also told off for not providing officials with a phone number where she could be reached for monitoring.

Meanwhile this assault case is ensuing, a judge has told Lindsay Lohan that she has to spend more time doing community service.

She was warned that she had to finish 480 hours of community service by next April.
