Josh Hutcherson dishes on his movie team-up with Jennifer Lawrence, including her being his "first real big kiss in a movie."

The two lead actors in the "Hunger Games" franchise spoke to CNN's Nischelle Turner as part of their promotion of the second installment of the series entitled "Catching Fire." During the interview, Hutcherson and Lawrence maintained the casual, honest-to-goodness vibe of the conversation, sometimes being candid on a few topics.

Like kissing in front of the camera.

"You just kiss," Jennifer tells Nischelle, and then admits, "I've had a couple bad ones."

What about the kiss with Josh?

"We're great together. We can really kiss."

Josh, for his part, says he does not have any bad onscreen kisses at the moment, and then proceeds to telling his co-star,

"You're my first real big kiss in a movie."

"Really?" Jennifer replies. "Oh my God, was I gentle?"

Josh answers with, "It was a little abrasive, if I'm being honest. A little shocking."

"It was very slobbery," she agreed.

Josh also talks with Ryan Seacrest June this year over the latter's radio show about that kiss with Jennifer in the first "Hunger Games" film.

"I'd say there's a natural stirring that happens in your body," the actor laughs. "If you're in the moment and you're in the scene, then naturally whatever naturally happens is what's supposed to happen."

That same month, the 20-year-old actor was spotted by the paparazzi kissing his girlfriend Claudia Traisac during a motorcycle ride in Los Angeles. The two met on the set of their upcoming film "Paradise Lost."

In the same interview with Nischelle, Jennifer talks about how she cried at a Whole Foods outlet the day the first "Hunger Games" movie came out. That day, she "had no idea I was famous yet or that anybody had seen the movie."

Whole Foods "had to call the police and I had to go down the cargo elevator and I was crying. And I saw my ex-boyfriend there and he's like, 'How's your life?' And I was like, 'Really bad.' It was the worst."

Jennifer then goes on to describe how she deals with fame just by, sometimes, saying no.

"Like if I'm at dinner and I'm eating and somebody wants me to stand up and take a picture -- that's actually helped with my anxiety, knowing that I don't have to say yes and I can say no. ... It is hard because you don't want to feel rude, but at the same time, I have to defend my life and my mental wellness," she says.
