Known In The '70s For: Singing the hits "You're So Vain" and "Nobody Does It Better"

Along with Linda Ronstadt, Carly Simon is considered one of the elite musical sex symbols of the '70s. Her first hit was "That's the Way I've Always Heard It Should Be," from 1971, which was followed by "Anticipation"—yes, the song from the old Heinz Ketchup commercials. Her 1973 single "You're So Vain" was the biggest hit of her career, a bitter attack on an ex-lover assumed to be either Mick Jagger or Warren Beatty, but Carly to this day refuses to say.

Carly was at least vain enough to know she was sexy and that couldn't hurt album sales. The cover of 1975's Playing Possum was her most risque: she's in a kneeling pose and her face is barely visible; instead we're meant to focus on her knee-high leather boots, thighs and ass cheekily protruding from a very short lacy shirt.
