Lady Gaga and Metallica are set to record an album together

Guitarist Kirk Hammett made a revelation accidentally for his plans for the Bad Romance singer was going to record vocals for an album planned for release in early 2019 by responding to a fan’s question on the social networking site.

And according to MetalDen.com, he replied ‘Gaga is gonna kill em all in the studio when she sings for us’, when asked about the possibility of a collab on the album – set to be called The White Album. The comment was apparently swiftly deleted by the Metallica star, fueling gossip that the singer is already lined up for a recording session with the band.

The first time rumours have been rife about the two iconic music stars hooking up. Despite awkward technical difficulties, the collaboration between the rock band and the Born This Way singer, er, rocked the music world in February, and fans wanted more too.

The plans for the two acts to work together again then came to surface when the rock band said she was the ‘quintessential perfect fifth member’ in an interview with Rolling Stone.

Drummer, Lars Ulrich said: ‘[She is the] quintessential perfect fifth member of this band. Her voice, her attitude, her outlook on everything is so awesome.

‘[The performance] was so effortless and organic and she just has the spirit of hard rock and metal flowing through her veins.’

He continued: ‘It comes really easy for her. There’s nothing contrived; she just has this super warm, easy energy.

‘We already started fast-forwarding to the next chapter when we can do more of this. It’s not one of those “20 lawyers, strategists and managers trying to force two people from two different worlds to figure out how to spend four minutes together on a national telecast”.

He then added: ‘Of any of these undertakings, this is about as organic and authentic as there’s ever been one. We’re just getting started.’
