Born Stephanie Harrison, after starting her career in fashion modelling, she posed in both Mayfair magazine and as a Penthouse cover girl.
McLean met British motorcycle racer Barry Sheene, in 1975, while he was on crutches following a racing accident. After divorcing her first husband, she and Sheene married in 1984, and had two children, a son and a daughter. The family emigrated to Australia in 1987, to try to ease Sheene's arthritis from his injuries. Sheene died of cancer in March 2003. McLean continues to reside in Australia.
