The 43-year-old actress passed away in her sleep Wednesday night at a rehab facility in California.

We spoke with Kelly”s agent who tells us the actress had just voluntarily checked herself in for treatment for an alcohol problem this past week … and was determined to clean herself up.

The agent tells us, “She had been fighting demons for a while and finally lost her battle.”

Sources tell us Lisa had been in and out of rehab centers hoping to kick her alcohol problem … and most recently fell off the wagon after a huge dispute with her ex-husband.

We”re told Lisa”s new boyfriend brought her to rehab again on Monday … but she went into cardiac arrest late Wednesday night and could not be saved.

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 TV shows and movies including “Amityville Dollhouse.”
