The two women have known each other for several decades and collaborated on Cher's hit "If I Could Turn Back Time" in 1989. Despite acknowledging the backhanded compliment, Warren was amused by Cher's comment. She also revealed that she had to beg Cher to take on her song, which was originally written by Warren.
