This year, Ellen DeGeneres decided to celebrate Halloween on The Ellen Show by rocking an incredible Sia-inspired costume — wig and all.
"Obviously you would not see Sia without her dancer Maddie [Ziegler], so please welcome my Maddie for the day, Heidi Klum," DeGeneres adds.
With that, supermodel Klum walks on stage, wearing a nude bodysuit and a wig, just like Ziegler did for Sia's epic "Chandelier" video.
And because no episode of The Ellen Show is without a dance break, DeGeneres and Klum go on to present "Chandelier" to the audience, with DeGeneres lip-syncing Sia's song while Klum fully commits to an all-out dance performance.
We're pretty sure this is one performance that would make even Sia and Ziegler themselves proud.
