It was the big finale of the Oscars, Lady Gaga and the legendary Liza Minnelli presenting the award for Best Picture. But fans were concerned to see the 76-year-old Liza in a wheelchair, and by her apparent confusion. Now her longtime friend Michael Feinstein is telling Inside Edition that she was left confused by last-minute changes from producers. “She was sabotaged,” he said, saying that she was made to appear onstage in a wheelchair against her wishes, at risk of being removed from the show.
