Shelley in a promo pic for Charlie's Angels 1979
Shelley became Angel no. 5 in 1979. She joined Jaclyn Smith and Cheryl Ladd (and occasionally Farrah Fawcett) in the 4th season of Charlie's Angels. Shelley played sophisticated intellectual Tiffany Welles, daughter of a Boston police chief who happened to be a friend of Charlie. At the time, Shelley was THE immensely popular Charlie Girl; and her Charlie Girl persona played a huge part in her getting the role. Producer Aaron Spelling loved the idea of the headline "The Charlie Girl Becomes A Charlie's Angel."
