What a job! After rolling around on the floor and peeking up Halle Berry's dress three weeks ago, Jimmy Fallon was back to his cheeky antics on Wednesday, July 30—this time turning somersaults with Heidi Klum.

The Tonight Show host showed supermodel Klum, 41, over to the crash mat, took his position on the floor for their acrobatic display, and instructed her to come stand over his head.

"It’s okay I'm not going to peek, I'm not going to peek. Look my eyes are shut," said a laughing Fallon.

"You promise?" asked Klum, sounding unconvinced.

Wearing a tight, nude-colored lace dress, the German model warily took her position, standing right over Fallon's head.

"I peeked, I peeked," he shouted, as the audience went wild.

"There's a gigantic mic-pack and antenna you know where," laughed Klum.

As the mom of four grabbed Fallon's ankles, he launched them into an acrobatic forward roll, Klum screeching with fear as she tumbled down the mat, trying to protect her modesty in her short skirt.

The pair managed a couple of rolls before collapsing. But not content with their performance Klum quickly took control and ordered Fallon into a different position.

"Now we're going to do the German roll, go lay down," she ordered.
