Actress Lisa Robin Kelly, best known for her role on That '70s Show, has passed away in California.

AmityvilleRaised in the historic New England town of Southington, Connecticut, Lisa made her big debut on the small screen in an episode of Married... with Children, before landing more boob tube roles in shows like Silk Stalkings, Murphy Brown, The X-Files, and more. In 1996 she made her one and only nude appearance, going top free in the 8th installment of the Amityville Horror franchise, Amityville: Dollhouse. It was brief, but boobiful.

Her wild blonde mane and sultry bad girl image made her a perfect fit for the role of Eric Foreman’s ultra-hot older sister on That’s ‘70s Show, although substance abuse problems eventually brought her career to a standstill.

Late NightKelly's agent confirmed that the actress passed away in her sleep Wednesday night at a rehab facility in California. Rock and roll all night in heaven, Lisa!
