Katy Perry named hottest woman of 2013 by Men's Health

New year. New hot women list.

John Mayer is one lucky guy because his reported gal pal, pop princess Katy Perry, tops MensHealth.com's list of hottest women of 2013. The website notes, "At only 28, she's already been nominated for eight Grammy awards -- including album of the year. Nobody, including us, could get enough of Perry this year. And for that reason, she is our sexiest woman of 2013."

In second place is "Ted" actress Mila Kunis because according to the site, "she's perfect."

"Mad Men" star Christina Hendricks landed in the third spot for her "hourglass figure, those pillowed lips and bedroom eyes."

And rounding out the top five is "Hunger Games" cutie Jennifer Lawrence -- "the world's greatest reason to get lost in the wilderness" -- and sexy staple Jennifer Aniston. Last year, MensHealth.com voted Aniston the sexiest woman of all-time. And she still has it: "Hardly any stars have been as ubiquitous on the world's magazine covers over the past two decades--and that shows no signs of changing," according to MensHealth.com.

Other beauties making the cut are singer Janelle Monae, actresses Natalie Portman, Amy Adams and rapper Azealia Banks.
