Former "That '70s Show" actress Lisa Robin Kelly has died at the age of 43, reports TMZ.

According to the website, the actress died in her sleep on Wednesday night at a rehab facility in California. Kelly had voluntarily checked herself into rehab for treatment earlier this week, her agent told the website, explaining that she "had been fighting demons for a while and finally lost her battle."

Kelly was best known for her role as the promiscuous Laurie Forman on FOX's "That '70's Show," though she only made headlines in recent years for a string of DUI and assault arrests.
