Heidi Klum is no stranger to costumes nor leotards: She's the reigning queen of Halloween and a supermodel after all. Thus, both of those fun elements came together in her latest look on The Ellen DeGeneres Show.

The America's Got Talent judge wasn't clad in her normal, leg-baring minis or high-fashion ensembles, but a dance-ready all-in-one. And Klum surely did bust out some serious moves, recreating Sia's showstopping "Chandelier" video as none other than 14-year-old dance phenom Maddie Ziegler. Host Ellen DeGeneres took the reigns as the Grammy Award-winning singer and songwriter—slipping on her two-tone black and white wig, tulle LBD, black leggings, and sneakers, of course.

Here’s half of my Halloween costume. Sia the rest tomorrow.

"As you can tell I'm Sia and the problem is, I can't really see you," DeGeneres explained. "I made this costume myself. I found some old loofahs backstage. And the bow is from a car I gave away recently."

"Sia and I have a whole lot in common: She's Australian and I married an Australian. We both like to swing on a chandelier, which is why I'm no longer welcome in Bed Bath & Beyond," the host continued. "Obviously, you would not see Sia without her dancer Maddie. So welcome my Maddie for the day, Heidi Klum."

Klum then leaped out onto the stage. "You know I love you and I'd do anything for you," she confessed to DeGeneres. "Let's just go for it." The performance to follow was legendary. Watch it in the video at top.
