She's been called the sexiest woman in the world — but Jennifer Lawrence showed off the other side to her kooky character during an appearance on MTV News on Thursday, Oct. 1, when she stuffed 10 marshmallows into her mouth, and then spat them out in a bowl!

The Hunger Games actress was joined in a forest with costars Josh Hutcherson and Liam Hemsworth for the last in series of campfire appearances on After Hours with Josh Horowitz.

And to make sure their final camping session was truly memorable, Horowitz asked his campfire guests if they'd take part in a game of Truth or Dare.

All agreed, with the movie stars opting for a truth question.

"What's your most annoying habit?" Hutcherson asked.

Lawrence was quick to respond. "Josh, with the cricking of his neck," she revealed, mimicking the sound he makes when he realigns his spine. "And he does spit bubbles when he's thinking," she added.

Then, eager not to leave herself out of the question she volunteered her own most annoying habit. "I don't wash my hands after I go to the bathroom," the unrepentant 25-year-old boasted.

"And then she likes to put her hands over your face," a grossed-out Hemsworth added.

Nobody had earned a dare, but Horowitz was keen to play the marshmallow game anyway and Lawrence, never one to shy away from a challenge, grabbed a bag of marshmallows declaring she'd be able to get at least eight in her mouth.

The stunning actress managed that, and more — before spitting them out of her mouth (complete with drool strings) into a bowl.

"That really reminds me of a date when I was 16, and I was chugging this Icee, which are like 90 percent air, and then I burped," she said, giggling at the memory. "And then it all reacted in my stomach and all this foam was like coming out my mouth," she added.

"I just took the top off [the cup] and all this foam was just pouring out of me and then [my date] looked at me and I was like [waves at date]. So anyway that totally reminds me of dating. I don't know why I'm single," she quipped.

Watch the whole hilarious moment above and listen to Lawrence admit another, unsavory toilet revelation about where she likes to pee when she goes to the bathroom with a girlfriend!
