Shelley became Charlie's Angel no. 5 in 1979 when she joined the cast of TV's biggest hit in the 1970s. Everyone was excited to see THE Charlie Girl/Supermodel become one of Charlie's gorgeous cherubs. Along with Jaclyn Smith and Cheryl Ladd, Shelley looked like she fit right in. Her wholesome sex appeal was just the boost the show needed after it slipped in the ratings in the season that passed.
