Mad Men star Christina Hendricks has been named Esquire's best-looking woman in America — and the red-headed beauty has a few words for men.

Hendricks —  who won the title over Megan Fox, Adriana Lima and, yes, Zac Efron with 30 percent of the vote —  graces the cover of the May issue, in which she pens "A Letter to Men" detailing what she really thinks about the opposite sex and what men need to know about women.
