Shelley appeared on the cover of the Charlie's Angels Annual for 1981, along with fellow Angels Jaclyn Smith and Cheryl Ladd. Shelley joined the hit TV series in 1979 during its 4th season. Charlie's Angels dropped significantly in the ratings during its 3rd season (dropping from #4 to #12 in the Nielsen ratings) but was still so much on the radar that the casting of Shelley as Kate Jackson's replacement on the show generated so much public interest. Shelley was a well-known Supermodel and her casting as Charlie's newest Angel was just perfect. She had style, class and looked great with Jaclyn and Cheryl. Everyone was so excited to see her on the show.
