MTV Movie Awards: From Natalie Portman and Mila Kunis To The 'Twilight' Love Triangle, These Are Your Best Kiss Contenders!

It's been a big year for blockbuster romance, but in an ocean of powerful kisses, only one is mighty enough to walk away from the 2011 MTV Movie Awards with the coveted golden popcorn for the Best Kiss category.

You can cast your vote for Best Kiss right now, but before you do, how about puckering up and refreshing yourself on some of the contenders? Keep reading for our rundown of this year's Best Kiss nominees!

Natalie Portman and Mila Kunis, "Black Swan"

At the height of Nina Sayers' trip towards a psychotic break, the up-and-coming and overly pressured dancer embarks on a drugged up night of passion with her colleague and rival Lilly — a memorable, if somewhat disturbing, first kiss.

Kristen Stewart and Robert Pattinson, "Eclipse"

It's not a stretch to say that these two are the favorites; after winning in the same category at last year's Movie Awards for their "New Moon" kiss, do the on-screen Bella Swan and Edward Cullen have enough heat to win two golden popcorns in a row?

Kristen Stewart and Taylor Lautner, "Eclipse"

Or will this be the year for Team Jacob fans to rejoice? Though he's the eternal underdog in the war for Bella's heart, the teen werewolf (along with his killer abs) pleads his passionate case to his fair-skinned love with what could go down as an award-winning kiss.

Ellen Page and Joseph Gordon-Levitt, "Inception"

Sometimes you don't need an epic sweeping romance story to win your way to the top. Though it's a subtle moment, Arthur's quickly stolen kiss from Ariadne speaks volumes about the dream thief's irresistible charm.

Emma Watson and Daniel Radcliffe, "Harry Potter and the Deathly Hallows Part 1"

Then there are the times when a kiss doesn't even have to be real to be dubbed the best kiss of them all. Jealousy is the name of the game when Ron beholds a terrible vision of best pals Harry and Hermione with lips locked in a loving embrace, leaving both the red-headed hero and the viewers themselves in a stunned moment of silence.
