The former That '70s Show and Charlie's Angels star died Monday night at age 65 at Cedars-Sinai Medical Center in Los Angeles, her longtime boyfriend Lance O'Brien told TMZ. Her death came hours after it was revealed she was alive following her PR rep's premature death announcement late Sunday night. Roberts had been hospitalized since collapsing at her home on Christmas Eve. O'Brien learned Monday that Roberts was still alive while discussing her "death" in an interview with Inside Edition. O'Brien said hospital staff had led him to believe Roberts had died, even though her eyes were still moving when he left her on Sunday. "When she saw me and I was there, I saw her eyes open," he told Inside Edition. "I felt good. I said, 'Hey, her eyes are opening. Her eyes are opening.' They told me that's just a reflex." Following the bizarre news, Roberts' That '70s Show colleague Ashton Kutcher informed co-star Topher Grace that "yo bro she's not dead" after Grace posted a tribute Monday evening. Roberts is best known for playing a Bond girl in the 1985 film A View to Kill, as well as for her TV roles as Donna's mother Midge Pinciotti on That '70s Show and as an Angel on the final season of Charlie's Angels.
