Josh Hutcherson finds it weird to kiss Jennifer Lawrence.

The 'Hunger Games' hunk gets the giggles when he has to switch on the romance for love scenes with the Oscar-winning actress - who plays fearless competitor Katniss Everdeen in the fantasy franchise - because they are such good friends in real life.

Asked if it's strange to have to seduce his pal Jennifer, he told Glamour magazine: ''It is. There are times when we've had to cut because we can't get through a take without laughing.''

The 20-year-old actor fell for his own girlfriend, actress Claudia Traisac, while filming upcoming thriller 'Paradise Lost' and he thinks it's natural to develop feelings for your co-stars.

He said: ''As far as I'm concerned, you're both actors, you understand each other's lifestyle, so it's a very natural thing to have happen.''

Josh is focusing on his current romance and doesn't dwell on his ex-girlfriends - mostly because he can't remember much about their dates.

Quizzed about his best date ever, he joked: ''The girls I've dated hate me a little because I can't remember anything about first dates or when we kissed. I have the worst memory in the world!''

After being cast as kind-hearted hero Peeta Mellark in 'The Hunger Games', the actor has seen his popularity soar and still can't believe how much attention he gets online.

Josh enthused: ''I don't think I'll ever get used to it. I have two-pointsomething million followers on Twitter, and if I say something, they all listen. It's crazy! I shouldn't be allowed that responsibility.''
