This is so sad.
It was confirmed last July that Justin Bieber's bestie Lil Twist had managed to wrangle the pair of musical superstars to duet on the song together… and now we have it here for your listening pleasure!
Just indeedy, the song leaked this morning — and it couldn't have come at a better time, honestly. It's going to ride Miley's VMA wave straight into everyone's shaking booty!
Ch-ch-check out Twerk (above)!!!!!!
What do U think?
