The whole world has been jammin' out to Meghan Trainor's "All About That Bass" - including Justin Bieber.

Biebs appeared on a new remix of the song shared by producer Maejor Ali. Bieber can be heard singing along to the song's catchy chorus, "I'm all about that bass, no treble. We gonna take it to a whole 'nother level," before launching into some other new lyrics.

*WARNING: Some explicit language

Guess the Bieb is all about that bass, no treble!
