The nominations for the MTV Movie Awards are out today, and we can exclusively announce the sexy lip locks up for the Best Kiss category! Robert Pattinson and Kristen Stewart lead the pack for their passion in New Moon just in time for them to start promoting Eclipse — it’s a great pre-birthday present for Rob who turns 24 tomorrow! Kristen is actually up against herself, also earning a spot for her The Runaways smooch with Dakota Fanning. Taylor Lautner joins his Twilight costars in the category, though not for Jacob’s tempting pout, instead for all his hot and heavy makeout sessions on screen with Taylor Swift in Valentine’s Day. Voting starts in 3 hours at 12 p.m. ET/9 a.m. PT at MovieAwards.MTV.com!
