#14: Frank Sinatra & Mia Farrow
His Age: 48
Her Age: 21
Frank Sinatra met Mia Farrow in the mid-1960s as she was emerging as a young actress and he was already an entertainment legend. Their relationship moved quickly, culminating in marriage in 1966 despite widespread concern about the age gap and power imbalance.

The marriage lasted just two years. Farrow later described feeling overshadowed by Sinatra’s dominance and career expectations, while Sinatra reportedly struggled with her growing independence. Their divorce became one of Hollywood’s most talked-about splits of the era.
