A new survey by Advertising Age reportedly crowns the singer's sultry black and white campaign for Emporio Armani -- including that commercial where she strips off an Armani dress -- the sexiest ad of the year.
And because an Angel couldn't be far from the top, Miranda Kerr nabbed the no. 2 spot with the Victoria's Secret bra campaign she starred in just months after giving birth to baby Flynn.
Rounding out the list: Lily Aldridge's work for Victoria's Secret, Bar Refaeli's playful campaign for Passionata lingerie's Spring/Summer 2011 collection, Heidi Klum's topless "Project Runway" ad, and more.
Whew! We need a cold shower.
