Jennifer Lawrence's snot dribbled onto Josh Hutcherson during kissing scenes in 'Catching Fire'.

The 22-year-old actress who stars as Katniss Everdeen in the 'Hunger Games' trilogy joked about some ''very hot'' scenes that she shot with love interest Peeta Mellark, played by Josh, that saw her in a less attractive light.

Talking at the San Diego Comic-Con, she said: ''Oh my God, we should have brought the clip with the snot ... I'll put it on YouTube or something, you gotta see it ... there's all this snot coming out of my nose, and when I go to kiss Josh, it connects with his mouth. So, yes, it'll be very hot.''

Josh added: ''There was a lot of slobber.''

Jennifer had trouble walking in her character's wedding dress during key scenes and she joked about her famous fall at the Oscars earlier this year, which saw her stumble as she collected the Best Actress prize.

She added: ''Wearing it was one of the hardest things I've ever done in my life, and you can tell, I think. It was huge. Five feet in circumference. I'm not good at walking in giant dresses, as we know.''

The second in the trilogy, 'Catching Fire', is set to be released in November this year.
