The legions of Beliebers have another handful of fans to add to their ranks, as Metallica have admitted that they're fans of the Canadian popstar.

J-Biebs recently posted a video in which he's and a friend are jamming on Metallica's famous song 'Fade To Black' and apparently this has gone down well with the legendary metal band.

Bieber has been quoted in the past as saying that Metallica are one of his favourite bands, saying: "I like Metallica's 'Fade To Black' and 'One'. It's edgy and emotional with those instruments and electric guitars and stuff." Quite, Justin.

Metallica drummer Lars Ulrich said: "Is it possible to have respect for him without being a Belieber? I think the kid's really talented and obviously to go through what he's going though at that early age must be a mindf*ck.

"So the fact that he still goes out there and does it, I admire that and I think he's super talented, so I guess I am kind of a Belieber. If he likes 'One', and Liam Gallagher likes him, Okay, there you go."
