That '70s Show star Lisa Robin Kelly died Wednesday in her sleep after going into cardiac arrest at a rehab facility in California, TMZ reports. She was 43.

Kelly, who played Eric Forman's (Topher Grace) sister Laurie on the sitcom, had voluntarily checked herself in to the facility to treat an alcohol problem earlier in the week, according to TMZ. It was reportedly the latest in a long line of rehab stints for the actress. "She had been fighting demons for a while and finally lost her battle," her agent told TMZ.

In addition to That '70s Show, Kelly also starred in the 1996 movie Amityville Dollhouse. She also had small roles on Murphy Brown, The X-Files and Charmed, among other television shows.

In July, Kelly's estranged husband, Robert Gilliam, was convicted of domestic battery against her. He served 35 days in jail and was sentenced to three years' probation, according to TMZ. She had filed for divorce from him earlier this summer.

Since 2010, Kelly has been arrested several times for charges including DUI, spousal abuse and assault.
