EXCLUSIVELisa Robin Kelly
-- who played Eric Forman's older sister on "That '70s Show -- has died ... TMZ has learned.
The 43-year-old actress passed away in her sleep Wednesday night in California.
Kelly had been in a downward spiral for the past couple of years -- she was arrested at least 4 times in the past 3 years for DUI, spousal abuse and assault.
Lisa had filed for divorce from her husband Robert Gilliam back in July -- seeking to end a marriage that was littered with allegations of spousal abuse, by both parties.
Besides "That '70s Show," Kelly had appeared in several movies and TV shows.
