Lisa Robin Kelly (who played Laurie Forman, Eric's sister on That 70's Show) died suddenly back in August, but her autopsy results have just been released.

The Los Angeles County Coroner has listed her cause of death today (Jan. 3) as, "multiple drug intoxication."

Her death was also ruled an accident and it was determined that the fatal drugs in question were taken orally.

Making this even more tragic, Kelly died while in a drug and alcohol rehabilitation center that she had checked herself into.

Revealed her rep at the time, "She was battling the addiction problems that have plagued her these past few years. I spoke to her on Monday and she was hopeful and confident, looking forward to putting this part of her life behind her. Last night she lost the battle."
