Earlier this summer, Zielger admitted that Sia was "starstruck" the moment she met the pint-sized dancer.

She told Vulture: "The first day I met her, she just came up and gave me a giant hug and said, 'I can't believe I'm with you right now! I'm such a big fan.' It was just so funny because she's a really big star and really successful singer and everything, and I couldn't believe that she was fan-girling over me."

As far as how she landed the role in her new video, Maddie says that Sia reached out to the show via social media. She said, "Sia was a fan of our show. She actually tweeted us, "Hey, Maddie, would you like to be in my new video for my new song Chandelier? I was just like, whoa, this is pretty cool."
