Mila Kunis has been crowned “Sexiest Woman Alive” by Esquire — and it’s not hard to see why.

Ever since breaking onto the Hollywood scene in That ’70s Show, the easy-on-the-eyes actress has been bewitching audiences with her dark beauty, comedic charm and down-to-earth demeanor. From rom-coms like Forgetting Sarah Marshall and Friends with Benefits, to her highly-acclaimed turn in the Oscar-nominated psychological thriller Black Swan, Kunis has proven both a big-screen and small-screen knockout — and one with some serious acting chops at that.

But it’s more than her sense of humor or haunting dramatic side that keeps fans coming back for more.

Kunis has a sex appeal that makes her loved by all — men want to date her; women want to be her.

From her sweet on-screen moments with now real-life beau Ashton Kutcher in That ’70s Show to her steamy between-the-sheets scenes with Justin Timberlake in Friends with Benefits, Kunis has puckered up for many passionate roles.

Who could forget her girl-on-girl, heart-racing moment with Natalie Portman in Black Swan? The rival ballerinas lock lips in a steamy make-out session and their unforgettable scene was nominated for Best Kiss at the 2011 MTV Movie Awards.

Given her new Esquire honor, Celebuzz is looking back at Kunis’ best on-screen make-out moments.
