"That '70s Show" actress Lisa Robin Kelly has died -- she was 43-years-old.
TMZ reports that Kelly passed away in her sleep at a rehab facility in California on Wednesday. Lisa's agent revealed to TMZ that the actress had voluntarily checked herself in to rehab earlier this week for treatment for alcohol. Her agent adds that Kelly was determined to get clean.
The actress, who is best known for playing Eric Formen's (Topher Grace) older sister on the popular comedy, had been in and out of rehab for substance abuse for quite sometime. Lisa had recently fallen off the wagon, after having an altercation with her estranged husband Robert Gilliam.
Robert was convicted of domestic battery just last month and sentenced to three years probation for beating Kelly last May. Reportedly, things got physical between the two because Gilliam wanted residual from her show. Lisa filed for divorce from Robert last July.
While the actress was in rehab, she went into cardiac arrest late Wednesday night and could not be revived.
Our thoughts go out to Lisa's family and friends. Lisa's friends and costars took to Twitter to share their condolences -- see their reactions below:
