Does 'Twilight' Have A Lip-Lock On The Movie Awards?

We'll see if RPattz and KStew nab their fourth prize over 'The Vow,' 'Potter,' 'Crazy, Stupid, Love' and 'Hunger Games' on Sunday.

This year's Best Kiss nominees are as diverse as they are titillating. Whether the smooch's setting was rain-soaked, in a cave, seven years in the making or post-marriage, the nominees for this consistently popular 2012 MTV Movie Awards category all deserve credit for their wonderfully cinematic tongue tangos.

Here's a look at this year's very competitive category:

Emma Stone and Ryan Gosling, "Crazy, Stupid, Love"

Much ado has been made over the all-around swoonworthy-ness of Ryan Gosling and the all-around likeability of Emma Stone. Putting them together in a romantic comedy where their first kiss involves an assertive, rain-soaked Emma Stone getting exactly what she wants made for one of the year's steamiest onscreen kisses. Not to mention Gosling's adept assist in the scene: He is a Best Kiss winner after all (for "The Notebook") and responsible for one of the best acceptance "speeches" in MTV Movie Awards history.

Emma Watson and Rupert Grint, "Harry Potter and the Deathly Hallows, Part 2"

Oh, young love. So angsty and confusing and frustrating and, in the case of "Harry Potter" characters Hermione (Watson) and Ron (Grint), too many years in the making. Though the big moment in the movie was different from how things went down in J.K. Rowling's beloved novels, you can still hear the collective sighs and squeals over their very long-awaited first lip-lock in the blockbuster franchise's eighth and final film, "Deathly Hallows, Part 2."

Jennifer Lawrence and Josh Hutcherson, "The Hunger Games"

Known affectionately to "Hunger Games" fans as the "cave scene," Katniss (Lawrence) and Peeta (Hutcherson) find themselves between a literal rock and a hard place when Katniss must venture out to fetch her teammate and would-be love the medicine that will save his life. Katniss' winning argument for risking her life is sealed with a kiss.

Kristen Stewart and Robert Pattinson, "The Twilight Saga: Breaking Dawn - Part 1"

"Twilight" fans will never tire of seeing kisses shared between their favorite onscreen couple, Edward Cullen and Bella Swan. And luckily for the fans, the three-time winners know how to get the job done, as demonstrated by their passionate, lengthy and very public display of affection after being announced as man and wife in "Breaking Dawn - Part 1."

Rachel McAdams and Channing Tatum, "The Vow"

What's more romantic than a devoted and doting husband? One who is charged with the very difficult task of making his wife fall in love with him all over again after she sustains severe memory loss from a traumatic accident. Such is the sweet and sigh-worthy setup for Channing Tatum and Rachel McAdams' heart-melting second first kiss in the romantic drama "The Vow."
