Shelley became Charlie's 5th seraph in 1979. She joined the cast of Charlie's Angels, one of TV's most iconic series. The original Angels were Kate Jackson, Farrah Fawcett and Jaclyn Smith. When Farrah left the show, Cheryl Ladd took over. When Kate left, Shelley took over. Then when Shelley left, Tanya Roberts took over. Each and every Angel had her own unique style and persona. Kate Jackson was the smart no-nonsense Sabrina Duncan, Farrah Fawcett was the sporty California girl Jill Munroe, Jaclyn Smith was the sultry and mysterious Kelly Garrett, Cheryl Ladd was the cute and sexy girl-next-door Kris Munroe, Shelley Hack was the classy intellectual Tiffany Welles and Tanya Roberts was the street-smart tigress Julie Rogers. They were all gorgeous and they were all loved by fans.
