Jennifer Lawrence Stuffing Marshmallows Into Her Mouth Is Oddly Entertaining

We totally don't want to gross-shame Jennifer Lawrence or anything, but the Oscar winner did make some rather alarming confessions yesterday. Lawrence joined her Hunger Games: Mockingjay - Part 2 comrades Liam Hemsworth and Josh Hutcherson for a round of Truth or Dare with MTV, and things got a little messy. Turns out the costars all have habits that would make Emily Post jump out of a window. Lawrence called out Hutcherson for cracking his neck and making "spit bubbles," but admitted she too has issues. "I don't wash my hands after I go to the bathroom," she revealed, proving the point by waving a finger under Hemsworth's nose and asking if it smelled like his mom. Oh, Jennifer. Prompted by a question by pal Amy Schumer, she also 'fessed up to peeing in a sink from time to time. And don't get her started on the time she burp-vomited out a frozen beverage on a date. "No wonder I'm still single!" she said. That brings us to the marshmallow challenge. Watch below to see America's Sweetheart ram 10 marshmallows into her mouth while cracking sex jokes. We're both amused and slightly nauseated.
