We already knew that Justin Bieber was 'All About That Bass,' but you have to listen to his R&B spin on Meghan Trainor's smash hit.

It all started when famed producer Maejor Ali came out with a super hot new remix of the track, infusing the tune with some seriously sick R&B/hip-hop beats. As he tells it, once Trainor and Bieber heard his "hood yet house" remix, "they asked me to pull my version down so that the collaboration could happen," he explained to Billboard. "And that’s the dopest part.”

Of course, the best part for us is practically all of it, especially when JB puts his smooth vocals to work on the incessantly catchy chorus. And yeah, we're totally digging his repetition of "We know that s--- ain't real, we know it's Photoshop," giving the track a little bit of a harder edge. Not to mention that it's actually pretty interesting to hear the song from a guy's perspective!
