We know Heidi Klum is gorgeous au naturel, but when prepping for each episode of Project Runway, it takes a whole team of stylists to make the supermodel camera-ready. In the clip above, she takes PEOPLE behind the scenes, where she has her hair and makeup done — and visits wardrobe. Klum goes through 40 different outfits over the course of one Runway season, and the wardrobe team pre-matches each look to the appropriate shoes and accessories for her. “I don’t mess anything up around here, OK?” she jokes. Hair and makeup for the models is done, of course, by the teams from Garnier and L’Oreal Paris, who share a bright room filled with beauty products. “It’s all much smaller than people probably think,” Klum tells StyleWatch of the small space. But the real fun happens in a break room, where Klum says the judges and mentor Tim Gunn “gossip around a little bit” and talk about the looks they’ve seen on the runway. However, the host has another favorite off-camera pastime: tickling Gunn! “He’s so ticklish,” she laughs. See more of the Runway backstage in the clip above! —Kate Hogan
