Her appearance on the popular late night talk show, which airs in Australia on ABC2, ended with the 31-year-old model, teacup designer and health advocate playing an American drinking game with host Jimmy Fallon.

''I’ve never played this game before but I’ve got to get into the American culture,'' Kerr said.

Prior to downing six beers during a match of Flip Cup, Kerr chatted about growing up in Australia, learning to drive when she was eight years old in a powder blue Valiant, and her mile high fitness tips.

''When I’m on an aeroplane, there is a couple of little exercises you can do when you’re sitting down,'' she said.

''You can tighten your ab muscles, you can clench and release, clench and release,'' she said while demonstrating the core exercises before offering her tips for a great gluteus maximus.

''And your butt muscles, you can do that. You clench and release, and then you can alternate,'' she said, rocking back and forth on her chair.

''Don’t do that on my show, I’m married. I’m a happily married man,'' a flushed-looking Fallon said.

After the fitness lesson, Kerr spruiked her Kora skincare line, which she claims is safe enough to be used by children.

''It’s certified organic, it’s very good for the skin and it rejuvenates the skin. It’s good for men and women and babies,'' she said.

''Yeah, I could start putting it on babies too,'' Fallon said as Kerr adopted the role of beauty therapist and performed a consult and facial live on air.

This is the second time Kerr has appeared on late night television with Fallon. She previously made a cameo on his former show Late Night with Jimmy Fallon during a game called Stand Next to Miranda Kerr.
