Emblem3 have made fun of Justin Bieber by posting a photo online of themselves naked with instruments.

As previously reported, images of the Canadian superstar standing in the buff with an acoustic guitar were recently obtained by TMZ.

Bieber was pictured playing his wooden instrument in front of his grandmother as an alleged thanksgiving prank.

X Factor USA group Emblem3 have now made fun of the photos by uploading a picture of themselves naked with some instruments.

The buff lads said: "Hey @justinbieber, we're in Canada ready for the jam sesh! #Emblem3."
