At 47, Bill Wyman, bassist for The Rolling Stones, started a relationship with 13-year-old Mandy Smith. Her mother consented! Bill and Mandy married 6 years later but it lasted one year. To make things weirder, Bill's 30-year-old son, Stephen, married Mandy's 46-year-old mother, making him a stepfather to his former stepmother. If Bill and Mandy had stayed together, Stephen would have been his father's father-in-law and his own grandfather.
