Since Ziegler and Sia have such a storied history of working together, here are seven of their most memorable collaborations:
1. “Chandelier” music video (2014)
This is the collaboration that started it all. The music video, which currently has over 1.6 billion views, sealed Ziegler's place as an up-and-comer and launched Sia into super-stardom. In live settings, the duo concocted several iconic performances, recreating the music video on The Ellen DeGeneres Show (with Sia standing in the corner) and at the 57th Grammy Awards with the help of Kristen Wiig.
2. “Big Girls Cry” music video (2014):
Choreographed by Ryan Heffington, Ziegler emotes in a fourth-wall shattering close-up where her exaggerated expressions add a frenetic energy to a relatively sedated Sia song.
3. “Elastic Heart” music video (2015):
The music video was controversial amid accusations of pedophilic undertones as Shia LaBeouf danced with Ziegler while both were dressed in nude dancewear. However, their Saturday Night Live performance gained acclaim as Ziegler flitted around Sia's shrouded frame.
4. “Cheap Thrills” music video (2016):
In the performance edit of the music video, Ziegler's silhouette leads a trio of dancers. She doesn't need dollar bills to have fun, if her energetic performance is any indication.
5. “The Greatest” music video (2016):
Ziegler smears a rainbow stream down her face at the beginning of a music video that was widely interpreted as a tribute to the LGBT victims of the Orlando shooting in 2016.
6. Sia's Nostalgic for the Present tour:
Billboard's Jason Lipshutz wrote at the time, "Having watched Sia’s same show sans Ziegler at Coachella in April, Maddie’s presence adds a mischievous energy, as if replicated movements can’t capture the heart behind those wide eyes and deranged smiles."
7. Upcoming Sia-directed movie starring Maddie Ziegler, Sister:
Sia spoke about the film at the Venice Days film festival, saying, “I was too embarrassed to tell anyone I wanted to make a movie, because I thought it would be seen as a vanity project, because I was a singer. ... [A]fter I made the 'Chandelier' video, I realized that I was pretty good at directing, so I felt a little bit braver.”
