It's not every day when an iconic supermodel reveals her runway secrets, so when Gisele Bündchen [1] opted to teach Jimmy Fallon [2] a thing or two about walking the catwalk, he listened. Appearing on The Tonight Show, the Brazilian beauty joked that, since she's retiring [3], the host could take her place in the fashion world. And that's when the fun really began.

Jimmy broke out a pair of blue studded heels, and Gisele offered some sound advice. "Put the chest forward," she told him. "Squeeze the belly in. Shake the hips!" And surprisingly, Jimmy nailed it — but it's something you'll have to see to believe. Watch the video above, then find out more about Gisele's leather pants [4]. Hey, Jimmy? We'll see ya at Fashion Week.
