Australian pop star Sia released her seventh studio album earlier this year, but it looks like she's already gearing up for something else. Late last night, Sia released a new song entitled "The Greatest," alongside a video featuring her frequent collaborator Maddie Ziegler. What's more interesting about the track itself, however, is that the version released to streaming services features a verse from Kendrick Lamar.

Sia is known for her high-profile collaborations, having worked with the likes of Kanye West and Adele on tracks, but Kendrick's verse still comes as a surprise. Fitting atop the song quite well, Kendrick delivers a typically high quality verse on the track.

Listen to "The Greatest" below, and check out the video for it (sans Kendrick's verse) below that.
