Metallica are Beliebers.

The 'Sad But True' heavy metal legends are impressed by 19-year-old teen heartthrob Justin Bieber - whose fans are affectionately referred to as Beliebers - after he said their tracks 'One' and 'Fade to Black' are his ''jams''.

Speaking to Q Magazine, singer James Hetfield said: ''Are we Beliebers? Yes.''

Drummer Lars Ulrich added: ''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 through at that early age must be a mind***k. 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, OK, there you go.''

Justin was recently filmed backstage at a concert humming the guitar solo to 'Fade to Black' while playing air guitar, accompanied by backing musician Dan Kanter.

Beady Eye singer Liam declared himself a Belieber after Justin came on stage two hours late for a concert in London.

He said: ''I've got his f***ing back, man. Anyone who goes on two hours late is fucking right in my book.

''''All these so-called rock bands that sit backstage going, 'Hey, let's wait 15 minutes'. F**k that, wait two hours and 15 minutes! No one will beat that, ever. So get off his back, man -- I am a Belieber!''
