The biggest shocker to come out of the MTV Movie Awards on Sunday night (June 5) was hands down that Robert Pattinson treated Taylor Lautner to a smooch almost as passionate as the ones in the Golden Popcorn-winning "Twilight Saga" films.

But while it came as a surprise to those of us watching the awards show, the stars of this year's nominated "Eclipse" said it was about time the two onscreen rivals shared a kiss.

"It was about damn time, man. It's been up in the air for about three years now. I think we've all been waiting for Rob and Taylor to kiss," Jackson Rathbone told MTV News when we caught up with him backstage at the Gibson Amphitheatre in Los Angeles. "We knew it was coming, and finally it did. Finally, they acknowledged their love for each other."

Rathbone's vampire brother Kellan Lutz admitted he was a bit surprised, but their co-star Peter Facinelli shared a little secret about how the RPattz/Taylor smooch went off without a hitch.

"They asked us to show them in practice," Facinelli said.

"We taught them everything they know," Lutz confirmed.

Nikki Reed chimed in, saying she wanted to see some visual proof of the tale Lutz and Facinelli were weaving. "Let's re-enact that!" she begged, but the duo passed, insisting Facinelli had already pecked Lutz on the cheek earlier in our interview.

Tinsel Korey hought the Pattinson and Lautner kiss was "totally sexy," but Kiowa Gordon said he "puked a little bit" when his onscreen enemies locked lips. BooBoo Stewart had "no comment," but Julia Jones at least "thought it was cute."

All seemed to have been smoothed over by the time Pattinson, Lautner and their co-stars took the stage to accept the Best Movie award, with Lautner teasingly giving his sparkly co-star a knowing look and a quick tap on the chin before throwing his arm around his shoulder. As Rathbone said, those two should be nominated for a special award at next year's Movie Awards for Best Man-On-Man Kiss.
