Clad in a corset and full skirt, the new mom, who gave birth to daughter Lou, with husband Seal, last month, smiled as she slowly took the runway for the surprise appearance.
Just Wednesday, Klum spoke of only hosting the show. "You have less pressure," she said. "You definitely have less pressure when you don’t shake your booty in front of millions around the world."
Klum added that she still had 20 lbs. of baby weight to lose: "I embrace that I have more curves right now. I’m definitely one of the heaviest of the bunch of the 30 girls in the show."
