Her latest album "This Is Acting" was released in January. Are you loving the song?
"She's the best. I'm so honored to be dancing with her for six weeks", Ziegler gushed to ET last month.
The Greatest, another one of the Australian bisexual singer-songwriter's killer ballads, stars 13-year-old dance star Maddie Ziegler in the video.
This time around, Sia recruited Compton-native Kendrick Lamar for her new single "The Greatest".
The talented teen performer has become Sia's alter ego on screen and stage since her award-winning 2014 single Chandelier.
But Ziegler dances through the house bringing the children to life, leaving a message of hope-and not giving up-in her wake.
The video, directed by Sia and Daniel Askill, takes place in some vague, dystopian future where children are homeless castaways against a monotonous, grey landscape. The rap is not featured in the music video, but is included in the version when streamed on Spotify or Apple Music, or purchased on iTunes.
'The Greatest (ft. Kendrick Lamar) is out now.
Sia is still capitalizing on the success of her single "Cheap Thrills", but it isn't stopping her from releasing an entirely new song seemingly out of nowhere.
But fans were still surprised when The Greatest lobbed, following the same guerilla marketing strategies which have proven so successful for Beyonce, Lamar and Frank Ocean this year. And aside from dropping the new tune, she also revealed the visual that goes along with it. The Nostalgic for the Present Tour will mark the singer's first time back on the road in five years, and we can not wait.
