52. Olivia Newton John
Hottest Moment: 1981, “Physical.” This early-80s megahit was emblematic of the decade in so many ways. The beautiful and toned Olivia prancing around, unashamedly objectifying musclebound weightlifters. This was a woman in control of her body and her sexuality. This was also a woman with that awful 80s short hair singing synth-heavy cheesy pop music. But don't kid yourself, you still would.
Where Is She Now: Standard stuff for a mostly-retired icon: Charity gigs and occasional mega-hyped concerts. And she's done Glee twice.
