Cathy Lee Crosby is the daughter of Hollywood actress Linda Hayes and Lawrence Welk Show announcer Lou Crosby. Crosby began her own showbiz career at five, appearing on her dad's local L.A. TV series, Crosbys' Calling. Like her sisters, Linda Lou and Lucinda Sue, Cathy Lee proved to be a superb athlete at an early age; before reaching the age of 21, she was a professional tennis player and recreational skydiver, windsurfer, and swimmer. Thus, she was uniquely qualified for the title role in the 1974 made-for-TV film The New, Original Wonder Woman. Intended as the pilot for a weekly series, Wonder Woman scored in the ratings, but was shot down by the critics; when a series did finally surface in 1976, Lynda Carter played the lead. Crosby cut her losses, made a few films in Europe (she is fluent in several languages), and returned to athletics. In 1980, she became one of the co-hosts of the popular "reality" TVer That's Incredible, a job she held down until 1984. Still hoping to be taken seriously as an actress, Cathy Lee Crosby made her off-Broadway bow in the 1988 production Almost Perfect; she has also remained active in a variety of charitable and prosocial organizations. Cathy Lee Crosby should not be confused with Live With Regis and Kathie Lee co-star Kathie Lee (Crosby) Gifford and she is not the daughter of Bing Crosby.
