One of the many perks of an acting gig is the possibility of a hot makeout session with a good-looking costar. And yesterday (July 30) Taylor Lautner and Taylor Swift both realized that dream.

The “Twilight” stud and the “You Belong with Me” songstress were spotted swapping spit on the set of their new movie “Valentine’s Day.”

And it must have been an enjoyable moment because afterwards Miss Swift launched into a mini-gymnastic routine including a cartwheel and a backflip.

With this pairing of two hot up-and-comers, it looks like “Valentine’s Day” is going to be a big hit among teen audiences as well as adults who will be coming out to see the great ensemble cast of Julia Roberts, Anne Hathaway, Jessica Biel, Bradley Cooper, and Ashton Kutcher.
