On the heels of her "perfect 10" fight with Donald Trump, Heidi Klum went head-to-head with "Tonight Show" host Jimmy Fallon in a hilarious game of "Box of Lies."
The key to winning the game was to correctly guess whether the opponent was lying about what was inside the other player's box.
The "Project Runway" host was up first, claiming that she had a box of butterflies with gum stuck on them -- which was, in fact, a bowl of miniature bottles of Fireball whiskey.
Fallon didn't buy her lies, so the pair celebrated his win by doing a shot!
For his turn, the comedian told Heidi that he had "a Jell-O mold with a bunch of Justin Bieber heads in it … doll heads." Nope ... all lies!
The game took a dirty turn when Klum told Fallon she had wax lips on a sheet of moss inside her box.
"We air at a certain time of night, but there's not way it's moss with a mouth on it," Jimmy said. But was the supermodel lying? Check out the video to find out!
