Watch All of Maddie Ziegler's Sia Videos in 1 Place

Sia debuted the video for her new song "The Greatest" this week. The single, which features Kendrick Lamar, is a tribute to the 49 lives lost in the Pulse Nightclub shooting in Orlando, FL, back in June. Once again, Sia enlisted the help of dancer Maddie Ziegler for the powerful visuals, and (once again) the 13-year-old knocks it out of the park. We've rounded up all the times Sia and Ziegler have worked together and proven that they're one hell of a dream team.
