On 19 February 2011, it was claimed by a number of press agencies that Nixon had an inappropriate relationship with a 17-year-old girl. The girl had previously been embroiled in a series of controversies involving players from the St Kilda Football Club, including one of Nixon's major clients, Nick Riewoldt. Nixon admitted to visiting the girl at her hotel room on at least three occasions and providing her with alcohol. The girl characterised the relationship as an "affair" and indicated that she was unaware at the time that Nixon was married.
