Justin Bieber's Purpose world tour kicks off next month and will span 50-plus dates over eight months. Dude isn't playing. So it's no surprise the pop star is getting in some much-needed rehearsal time before the tour begins, particularly on the choreography side.

Late last night, Bieber shared some footage from the dance studio of him and his backup dancers putting in work to... Young Thug's "Best Friend"? It's unlikely he will actually use this song on tour, though the connection isn't all that out of the blue. Bieber and Thugger linked up on Travi$ Scott's "Maria I'm Drunk" off Rodeo, and their chemistry was undeniable. Plus, you can't hate on him wanting to get down to this standout track off Slime Season.

If we're lucky enough, maybe Bieber and Thug will collaborate again on Slime Season 3. That's his best friend, that's his best friend.
