Louise Fitzgerald Wightman (née Johnson), better known as Lucy Wightman (born June 18, 1959 in Lake Forest, Illinois), is a writer, photographer, and blogger who became known in the 1970s and 1980s in her previous career as a former Boston and Providence area exotic dancer, radio talk show host, and award-winning bodybuilder. She performed under the stage name Princess Cheyenne in Boston`s red light district. She was an object of media interest because of the juxtaposition of her education, intellect, and class background with her career and stunning appearance. In the spring of 2007, she again attracted public interest, this time for being convicted of practicing psychology without a license in two south shore Massachusetts communities.

In 1979, Wightman was engaged to the singer Cat Stevens, but the couple broke up due to her career commitments and his conversion to Islam. After the breakup with Stevens, Wightman married and divorced twice; she had a daughter named Victoria (Torri) with her second husband Donald Wightman, a Boston police detective and head of security for the rock band Aerosmith. On May 16, 2006, Torri died as result of injuries sustained in an automobile accident in Plympton, Massachusetts. She was only 16 years old.
