16. Shannon Tweed
Hottest Moment: 1982, Hot Dog the Movie. As Sylvia Fonda, Shannon was there to provide boobs, a welcome respite from the heavy plot of this ski slope comedy. She went on to be naked in numerous other art films. She was one of Playboy's most frequent posers: as Playmate, Playmate of the Year, and semi-lesbian with her younger sister Tracy.
Where Is She Now: On the reality TV show Gene Simmons Family Jewels, playing the Kiss lead singer's still-hot wife. Which she is.
