Shelley in 1979
Shelley became Angel no. 5 in 1979. She was already a Supermodel by then and was known all over the world as THE Charlie Girl. She auditioned with the urging of her manager at the time; and eventually got the part, beating out almost 150 other candidates. Her first call went to her mother who was so excited; but it was her youngest sister Babe, a big fan of the series, who was the most excited.
