Edward's on Team Jacob! And vice versa!

Robert Pattinson and Taylor Lautner upended years of Twilight romantic rivalry at Sunday's MTV Movie Awards in a most unexpected way. When Pattinson, 25, and real-life love Kristen Stewart won the popcorn trophy for Best Kiss (in Eclipse), they teased the audience that they might finally lock lips onstage. (They faked out fans at last year's bash.)

But..."I just think there's someone else in the audience who I think will appreciate it a little more," Pattinson joked. See more photos of the Breaking Dawn cast at the MTV Movie Awards.

With Stewart, 21, egging him on, the British star (who plays vamp Edward Cullen in the series) rushed into the audience and planted huge kiss on Lautner, 19, (werewolf Jacob Black) as fans squealed with delight.
