Watch the pair's electrifying video for Cheap Thrills
Turn it up and prepare to feel all the feelings (including, spoiler alert: a longing to punch through some windows).
To recap: Ziegler and Sia embarked on a trilogy of beautifully haunting music videos in 2015. They collaborated on the videos for Chandelier, and Elastic Heart (famously also starring Shia LaBeouf) and Big Girls Don't Cry (all directed by Sia and Daniel Askill).
Then, in February 2015 the pair performed with Kristen Wiig at the Grammys and it was epic. Wiig and Ziegler were dressed identically and killed their dance set that featured a mesmerising series of high-drama moves.
A strong aesthetic characterises everything Sia and Ziegler have done to date. Costumes are simple - frequently just plain bodysuits and the severe bobbed wigs that have become the singer's signature - and the neglegted-looking sets suggest the potential for something chilling.
The choreography, which is always utterly compelling, is courtesy of Ryan Heffington. Ziegler executes the eery and intense routines perfectly. Add to that Sia's inimitable sound and you have art that is achingly cool.
