The 67-year-old singer-and-actress is close friends with Jack, 76, and insists he is wonderful to be around because he's so much fun.
Despite his reputation as a heartbreaker, Cher insists Jack just loves to be around women because he relates to them.
Speaking with fans during a Facebook Q&A, she said of Jack: ''He's a love. I've known him my whole adult life ... He is more amazing then people think he is, and so kind, and he loves women. Actually he loves hanging out with women.''
Cher also revealed Jack - who she starred with in the 1987 movie 'The Witches of Eastwick' - gave her a hand-painted model of a bull as a gift for her birthday in May.
The 'Believe' singer said: ''He painted a little bull for me for my birthday because we are both Tauruses. Taurus people rule!''
During the online interview session, Cher also admitted to missing her late ex-husband Sonny Bono, whom she performed with as the duo Sonny and Cher until their bitter divorce in 1975.
She said: ''I think about him a lot sometimes. There are things about him that I miss.''
Although she later caused a stir on the social networking site by joking that her ex - who had a string of affairs during their eight-year marriage - was in hell.
When asked by a fan, ''If Sonny Bono were still alive today, but you only had a minute to talk to him, what would you say?'', Cher quipped: ''How hot is it where you just came from?''
