This supermodel isn't afraid to chug!

Miranda Kerr and Jimmy Fallon faced off in a fierce game of flip cup on "The Tonight Show" on Thursday night.

But first, the 31-year-old beauty taught the late night host some exercises he can perform while sitting down.

"You can tighten your ab muscles, clench and release," Kerr explained. "And your butt muscles, clench and release, clench and release."

"I’m happily married!" Fallon joked.


Then, the duo battled it out in the classic drinking game. Fallon even played with splotches of lotion from Kerr’s new skin care line on his face!

Watch the beer-filled battle above to see who took home the Flip Cup trophy!
