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 [1], back in June.

We've rounded up all the times Sia and Ziegler have worked together and proven that they're one hell of a dream team.
