UPDATE: According to TMZ, Lisa's boyfriend took her to the hospital on Sunday, August 11, where her blood alcohol level registered at an alarmingly high .34. The next day, she was admitted for alcohol abuse treatment at Pax Rehab House in Altadena, California. Pax told law enforcement they did not give Lisa any drugs, and no drugs or alcohol were found in her room. There was reportedly no obvious sign of trauma, and her death is still reportedly being called "a mystery." An autopsy was completed on Monday, August 19.

Original story:

That '70s Show actress Lisa Robin Kelly has died, according to reports from TMZ.

The site reports that the 43-year-old passed away in her sleep on Wednesday night (Aug. 14) in California.

In the past few years the actress has been arrested at least four times — once for a DUI, once for spousal abuse, and finally for assault. She filed for divorce from her husband Robert Gilliam in July.

Lisa's agent told TMZ that within the past week she had voluntarily checked herself in for treatment for an alcohol problem, stating, "She had been fighting demons for a while and finally lost her battle." Sources say that she died of cardiac arrest, but that has not been officially confirmed.

On the show, Lisa played wild-child Laurie Forman, the older sister of main character Eric. She appeared on the show for the first five seasons; when she left, Laurie was sent off to beauty school. She was replaced by Cristina Moore in the show's sixth season.

Though she appeared in smaller roles on other TV shows and in movies, Lisa is most recognized for her time on the long-running sitcom, where she always brought the laughs as Eric's snarky, evil older sister. We've collected some of her funniest moments from over the course of the show to honor her memory.
