It looks as though Maddie Ziegler will be sharing the spotlight again with another celebrity star for Sia's upcoming music video. There's a new rumor suggesting that supermodel Heidi Klum might be joining the Dance Moms star for the Aussie chart topper's latest music clip.

Ziegler opened up about working with Sia, calling the collaboration the best experience of her life so far.

In an interview with Billboard back in February, Ziegler admits that she is getting more recognition thanks to her collaborations with the often-shy singer. The pint-sized dancer also starred in Sia's music videos for "Elastic Heart" and "Chandelier."

"I never knew that I would be performing on talk shows with Sia," Ziegler said. "It's just crazy getting to do all of the fun experiences I did. I thought it would just be a little video, just to have fun with it ... but it was huge!"
