Shelley in a writeup from 1979 for Activa mag
Shelley was already a world famous Supermodel in 1979. But when she joined the cast of Charlie's Angels, she became even more famous. Interest in her and everything about her was at an all-time high; but Shelley was determined to keep her private life private. So writeups about her determination to keep her private life private were written. One writeup about her on the Spanish-language mag Activa even had the title "Shelley Hack: The Famous Refuses to Talk About Her Past". Shelley prevailed though. She's one of Charlie's most low profile Angels.
