It's that time of year! Ellen DeGeneres got in the Halloween spirit with special guest Heidi Klum during her talk show on Monday, October 31. The host, 58, dressed up as Sia (wig and all!), while Klum, 43, played the singer's lead dancer, Maddie Ziegler.
"As you can see, I'm Sia. And the problem is I can't really see ya," DeGeneres, who dressed as a Kardashian sister last year, joked to the crowd. "I made this costume myself. I found some old loofas backstage and it was not that hard to make. And then 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 [Portia de Rossi]," she added. "And we both like to swing from a chandelier, which is why I am no longer welcomed at Bed Bath & Beyond."
Klum, meanwhile, wore a nude one-piece leotard to copy the look Ziegler donned in Sia's 2014 music video "Chandelier." "You know I love you and would do anything for you," Klum said.
The two then re-created the popular video, which has garnered more than one billion views since its release. DeGeneres lip-synched while Klum danced all around the stage.
The America's Got Talent judge loves Halloween — and it shows. Each year, she comes up with the most extravagant and detailed costumes that take hours to put together. Some of her most memorable moments include her 2014 butterfly ensemble and her old-lady disguise in 2013.
Once again, Klum has something big up her sleeve this year. "With all the election going on I thought I'm going to be Donald Trump, but my hands are too big. So, I had to rethink this whole thing," she joked to DeGeneres.
Last week, Klum teased her costume to Us Weekly. "My theme is going to be a German theme, and it’s going to be made in Germany," she revealed while attending the AmfAR Inspiration Gala in L.A. on October 27.
"It’s not the most comfortable thing. When you’re like a butterfly, like I had these eyes, I had batteries inside of the eyes so it glows. So I only see a little bit and I have the battery pack. It’s not all that glamorous from the inside, especially when it all comes off," she added. Last year I was Jessica Rabbit. It took two hours to dissemble that! I’m in a hotel room with these four guys ripping these boobs off me, that butt off me, all this stuff that I had on my face. I mean, it’s not pretty."
