Shelley joined the cast of the phenomenal hit TV series Charlie's Angels in 1979. The series was entering its 4th season and had experienced a sharp decline in the Nielsen ratings (from 4th over-all in the 2nd season to 12th over-all in the 3rd season). As it was still within TV's top 20 shows, nobody was too worried about the recent ratings decline; plus, the Angels were as popular as ever as evidenced by the ever-increasing worldwide public interest in the cast - in both the previous members as well as the newest ones. Shelley was already a Supermodel when she was cast and was known all over the world as THE Charlie Girl, Revlon's "it" girl. And the headline "THE Charlie Girl Becomes A Charlie's Angel" was just what the show needed to gain even more viewers and popularity. Everyone loved THE Charlie Girl and was excited to see her fight crime alongside incumbent Angels Jaclyn Smith and Cheryl Ladd. For the new season, the Angels were going to be the most fashionable crime-fighters on TV. "We're bringing back the glamour," executive producer Aaron Spelling proclaimed. "Suddenly, it's 'in' to be well-dressed. I'd love to see Charlie's Angels become a fashion plate show," Spelling told People magazine in 1979. So each Angel had an average of 8 costume changes per episode. And Charlie's fashionable new Angel team debuted at no. 1 in the ratings as Shelley's 1st episode "Love Boat Angels" topped the Nielsen ratings the week it was aired.
