Lisa Robin Kelly, who was most well known for her role as Eric Forman's older sister on "That '70s Show," died Wednesday at a California rehab facility. She was 43.

According to news reports, Kelly checked herself in to the facility earlier in the week to deal with an alcohol problem. The troubled actress has been arrested at least four times in the past three years for DUI and spousal abuse charges.

"Unfortunately Lisa Robin Kelly passed away last evening," her agent said. I spoke to her on Monday and she was hopeful and confident, looking forward to putting this part of her life behind her."

The actress' cause of death has not been issued yet and no death certificate has been issued either.

Kelly had voluntarily checked herself into a treatment facility earlier this week where she was "battling the addiction problems that have plagued her these past few years," according to her rep.

In addition to "The '70s Show," Kelly had guest roles on shows including "Days of Our Lives," "Murphy Brown," "Married With Children" and "The X-Files." She left "That '70s Show" during the show's third season, and reappeared for a few episodes in the fifth season.

She appeared in films including "Amityville: Dollhouse," "Jawbreaker" and "Clubland."

Born in Connecticut, she graduated with an acting degree from Depaul U. She recently filed for divorce from her husband Robert Joseph Gilliam, with whom she had a rocky relationship.
