Sia has teamed up with Kendrick Lamar to prove that she's "The Greatest." The enigmatic pop star released a new song of that name tonight that features a short but inspiring eight-bar verse from the Compton rapper.
She also released a video for the tune (for some reason, minus Lamar's contribution) that can be seen here. The clip features Sia's frequent stand-in Maddie Ziegler and a whole bunch of face-painted children escaping from a not-very-well-secured jail cell and running around a creepy old house, where they find…more people in face paint.
Sia's most recent album This Is Alive, released this past January, consisted of songs she originally wrote for other artists. It gave the singer her very first number one hit as an artist earlier this summer with the song "Cheap Thrills," featuring Sean Paul.
