Crosby was married at age 21 but divorced within two years. She was in a relationship with football star Joe Theismann throughout the early 1980s. Their romantic relationship ended in 1991, after which she sued him for $4.5 million because he "abandoned his promise to financially support her." Theismann responded with a countersuit, ultimately leading to both settling out of court. According to her autobiography, Let the Magic Begin, when Theismann sued for half of her assets, Crosby declared bankruptcy to stop his litigation, although these allegations have not been confirmed by other sources and the lawsuit documents were kept confidential.
