Taylor Lautner and Taylor Swift's First Kiss Details Revealed!

Find out about the the day Tay-Squared locked lips. Plus, is there really a Valentine's Day sequel already in the works?

What's the first thing Taylor Lautner and Taylor Swift had to do when they started shooting Valentine's Day?

Lock lips!

"I always start with the kissing scenes," director Gary Marshall told me at last night's Hollywood premiere of the star-studded romantic comedy. "The first thing they did was kiss."

So how did it go?

"The first three were nice," Marshall said. "By the fourth I think they started going together. I don't what the hell happened, but somewhere in the fifth or sixth take they were dating."

Marshall also confirmed reports that there's already a Valentine’s Day sequel in the work that will center on New Year's Eve.

"They're making me the holiday director," Marshall cracked. "I'm also going to do Flag Day [and] Arbor Day. Now, for all the holidays, I'll be doing something."

While Marshall says he's far from casting part two, he's already got Lautner on the brain. But that may be tough.

"He's booked until like 2020," Marshall said. "He's too busy."

But Marshall promises he'll let the Twilight star do things not other director will allow. "That Taylor can take a grape, throw it up in the air, do a flip and then catch it in his mouth," Marshall joked. "Nobody will let him do that in a movie—I'm gonna let him!"

Meanwhile, the red and pink carpet decorated with huge heart motifs (see it here on Twitter, @marcmalkin) felt more like an awards show than a premiere because it was jammed packed with stars like Julia Roberts, Bradley Cooper, Anne Hathaway, Eric Dane Rebecca Gayheart, Jessica Alba, Patrick Dempsey, Ashton Kutcher, Demi Moore, Topher Grace, Emma Roberts, Carter Jenkins, Jewel, Jamie Fox and Mr. Lautner.

Jennifer Garner attended without hubby Ben Affleck. Jessica Biel was also sans Justin Timberlake. But that's OK—JT was at a private screening of the movie that Biel recently held for her family on the Warner Bros. lot. 

Swift was a no-show because she's on tour in Australia.

The afterparty across the street from Grauman's Chinese Theatre was held under a large white tent with crystal chandelier-like fixtures hanging from above. Not only were there roses everywhere, but there was, of course, some yummy Valentine's Day-inspired chocolates from Godiva.
