Upon the announcement of Shelley's Angeldom in 1979, almost immediately, tongues began wagging about how Charle's new Angel trio didn't get along, how the Angels set was in turmoil. Writeups began to come out about Cheryl not wanting Shelley in the show because she's blonde as well, about how Jaclyn not wanting Shelley cast because she was competition for the "classy Angel" title. One tabloid even said that Shelley wanted to make Cheryl and Jaclyn her slaves. The stories were numerous and many of them were ridiculous if not hilarious. The truth is Cheryl and Jaclyn both felt comfortable with her and knew they could work with Shelley. Jaclyn even said she was the perfect fill in for Kate Jackson.
