With the final stretch of summer upon us, Sia is kicking off the fall with her new song "The Greatest," which features a verse from none other than Kendrick Lamar.

The singer had been teasing the collaboration in recent days, but the track officially arrived early Tuesday morning, with an accompanying video (sans Lamar). 

"The Greatest" arrives just weeks after Sia's "Cheap Thrills" was named Variance's 2016 Song of Summer. And as of this writing, it remains No. 3 on Billboard's Hot 100 chart in the U.S.

Directed by Sia herself alongside Daniel Askill, the clip stars Maddie Ziegler, with choreography by Ryan Heffington.

Watch the video and hear the Lamar-featuring version below.
