Lisa Robin Kelly, the actress who played Laurie on “That ’70s Show”, was found dead in a California rehab facility on Wednesday night. She was 43 years old.

Kelly has had a troubled past pretty much since she’s been in the acting world; she left “That ’70s Show” for a while–her character written off to go to beauty school–because of a drinking problem, then found herself in headlines several times for various arrests on drug and domestic abuse charges.

Kelly’s most recent arrest came in June, when she was cited for driving under the influence after an officer spotted her car stalled on the side of the road. She was taken into custody and later released on $5,000 bail.

Kelly’s agent told TMZ that she had only recently entered the rehab program to get help for her alcoholism.

“She had been fighting demons for a while and finally lost her battle,” he said.

The cause of her death hasn’t been released yet, but sources say she went into cardiac arrest in her sleep on Wednesday night.
