My mom has been telling us forever that she babysat for Cher. My daughters think my mom is crazy, but my mom insists it is true. My mom claims that she lived next door to Cher's grandma Mrs. Abraham and that Cher's moms name in l945 was Gohar. She says Cher's dads name is John Sarkisian and that Cher's grandma lived next door to my mom on 47th ave. in San Francisco. I am so curious to see if any of her story is true!
