Actress Emma Roberts spills the beans on her 'Valentine's Day' co-stars Taylor Swift and Taylor Lautner, and their make-out scenes in the upcoming romantic comedy.

Even though she didn't share any lines with the 'Twilight Saga: New Moon' actor, she did make sure she was on set to catch him in action. "They just had to make out," Emma tells MTV of the two Taylors' scenes together. "That's all I saw. Then I left."

Asked if all she did was watch them kissing, the 'Nancy Drew' star admitted she did spend some time with the pair. "They were both pretty cool. I hung out with them a little bit."

While the roles that they're playing haven't been revealed, rumors are circulating that Taylor a deux are playing their high school's prom king and queen. They've also both been photographed wearing gym clothes.

'Valentine's Day,' which will hit theaters in February -- just in time for Valentine's Day, natch -- also stars Julia Roberts, Patrick Dempsey, Jessica Biel, Anne Hathaway, Jamie Foxx and Bradley Cooper.
