[WATCH] Jimmy Fallon, Heidi Klum: ‘Tonight Show’ Host Peeks Up ‘America’s Got Talent’ Judge's Dress in ‘This Is How We Roll' [VIDEO]

Supermodel and judge from NBC's hit series America's Got Talent, Heidi Klum, stopped by another NBC hit last night, The Tonight Show Starring Jimmy Fallon. Following her interview with Fallon, the comedian and talk show host invited her to play a round of This Is How We Roll.

After making their way to the mat, Fallon joked, "I'm not gonna look. I promise," while lying down. "I'm not gonna peek. I promise!" As Klum stepped over him, skirt and all, Fallon commented, "Okay, I peeked."

He claimed to be joking but we're not so sure. After all, it is a once-in-a-lifetime opportunity.

Joke or not, however, Klum didn't seem to mind, teasing, "Have a look. Peek! You know what it is? It's a gigantic mic-pack with an antenna you know where."

During their roll, the two appeared to get a few somersaults in there before breaking the stride. When they did, Klum brought the host back to the starting point, saying, "Now we're going to do the German roll." You know, where you lay down on top of one another and roll like a log.

Check out the video from The Tonight Show below:

From the looks of it, we think we prefer the German roll. And it's pretty safe to say Fallon did too, considering he followed up with, "That's how we roll!"

He later joked that he was going to be in trouble with his wife later on. So, we'll have to wait and see if This Is How We Roll continues to be a running Tonight Show bit in the future.
