On 2 June 1989, aged 52, Wyman married 16-year-old Mandy Smith, whom he had “fallen in love with” when she was 13 and, according to Smith, had a sexual relationship with when she was 14.[45] The couple separated two years later and finalised their divorce two years after that.[46][47]

In 1993, Wyman’s son Stephen Wyman married Patsy Smith, the 46-year-old mother of Bill’s ex-wife Mandy Smith. Stephen was 30 years old at the time. Consequently, the ex-Rolling Stone became his own son’s ex-son-in-law, the father-in-law of his ex-mother-in-law, as well as the stepgrandfather of his ex-wife.[50]
