Shelley first became famous as THE Charlie Girl in 1976. Hand-picked to represent the Revlon brand, she was the embodiment the brand's ideal – gorgeous, sexy and young. Many of the Charlie ad campaigns and commercials also involved Shelley's then boyfriend, photographer Steen Svensson, and renowned hair stylist and makeup artist Rick Gillette. Rick recalls, "Shelley Hack was really the perfect girl for Charlie." Revlon shot numerous Charlie commercials with her alongside famous singers singing the catchy jingle. One of them was with Mel Torme and it was filmed in 1978 on a yacht docked on the La Seine, in front of the Cathedral de Notre-Dame de Paris. Male supermodel Matt Collins appeared at the end of the commercial as her date on-board. By then, Charlie was the #1 fragrance in the world (the first American-made international bestseller) and Shelley THE Charlie Girl had catapulted to icon.
