Last night (July 17) on 'The Tonight Show With Jimmy Fallon,' Australian supermodel Miranda Kerr and Fallon faced off in a down-to-the-wire battle of the classic bar game, Flip Cup.

Kerr had stopped by to promote her KORA Organics skincare products, as part of Fallon's nightly tradition of playing games with guests, was introduced to Flip Cup -- during which she claims she's never played the game before.

Given her most likely strict diet regimen in order to maintain her model figure, it's probably not surprising that she doesn't have much experience chugging beers for the purpose of winning bar bets. But as you can see in the video, she doesn't do too badly in what is supposedly her first time.

The winner of the game barely edges the other person out, as it becomes a close fight as they both near the final red cup. Who won? Click on the video above to find out!
