Jennifer Lawrence Dishes On Kissing Her 'Mockingjay' Co-Stars

Pucker up.

There are certain risks that come with filming a major movie. There's the stunt work, constricting costumes, long hours spent in the makeup chair...

And then there's the risk that comes with excessive makeouts.

"We all have herpes," Jennifer Lawrence joked at the London press day for "The Hunger Games: Mockingjay - Part 1." As co-stars Josh Hutcherson and Liam Hemsworth, both of whom she's locked lips with on-screen in previous installments laughed, she said, "all of us claim it's not us."

"See?" Hutcherson says, tugging down his lip.

Indeed, Lawrence's character Katniss not only has to make difficult choices about whether to act as the face of a (Hunger) game-changing revolution in rebellion-torn Panem in the latest installment of the "Hunger Games" series, she also has to work toward choosing which of her paramours she'll end up with. Will it be Gale (Hemsworth), her best friend and hunting companion, or Peeta (Hutcherson), her Hunger Games co-victor and long-ago savior?

"Sorry, herpes is not a joke, it's a disease that ravages the world," Lawrence clarified in the interview, even as Hutcherson continued to insist, "I have herpes."

Another non-medical risk Lawrence took in "Mockingjay": singing on-screen. In an unguarded moment in the film, Katniss sings a song her father taught her, "The Hanging Tree." The song becomes a sort of anthem for the rebels.

She's fought and kissed and done all sorts of daring things on screen, so a little song shouldn't be much to Lawrence, right?

"No, I hate singing, and I'm terrified. I've never sang in front of anyone or people, I don't like that," she said. "That was a terrible day for me."

"The Hunger Games: Mockingjay - Part 1" flies into theaters November 21.
