Shelley in a promo pic from 1979
Shelley joined the cast of Charlie's Angels during it's 4th season and was stunned and delighted with the opportunity she got. It was previously reported that Barbara Bach got the part and that was all over the entertainment news at the time. David Doyle, who played John Bosley in the series, even began researching about Ms. Bach, thinking she would be his new co-star. But the mistake was quickly corrected and it was announced that Shelley got the part. "THE Charlie Girl is Charlie's newest Angel" became the latest entertainment headline and Shelley's casting was announced in the evening news. Everyone was excited to see the Supermodel work for Charles Townsend and get the bad guys.
