Lisa Robin Kelly, best known for playing Eric Forman's attractive and promiscuous older sister Laurie on That '70s Show, was found dead last night at a California rehab facility. She was 43.

TMZ reports that Kelly apparently passed away in her sleep.

Since starring in That '70s Show, the actress has made repeat appearances in the tabloid press for her troubles with the law.

She was arrested a number of times over the last few years for both DUIs and domestic assault.

Kelly had just recently filed for divorce from her 61-year-old husband, and entered rehab voluntarily to get her life back on track.

"She had been fighting demons for a while and finally lost her battle," her agent told TMZ.
