Give me fuel, give me fire, give me… Lady Gaga?
Metallica drummer Lars Ulrich has offered the 'Poker Face' singer a place in the band, following their well-received performance together at the Grammy Awards earlier this month.
Speaking to Access Hollywood, Ulrich said the band's "got a new lead singer".
"Well, a new co-lead singer is a better way of saying it. We were talking earlier about maybe making her a permanent member of Metallica, and being a five-piece from now on, so we'll see."
Even if she's too busy to join them in the studio, wherever Gaga may roam, she's always welcome to join the 'Enter Sandman' rockers on stage.
Normally a pop singer, Gaga impressed fans of the band on 'Moth Into Flame', taking over the lead when singer James Hetfield's microphone failed.
Ulrich's long been a fan, saying she "killed" at the Superbowl half-time show.
"I think that at a time right now where everything in this country is so divisive, the one thing that everybody could agree on last week was that she just nailed it better than anybody ever, so it was awesome."
Metallica are about to embark on the next leg of their WorldWired tour, in support of their latest record Hardwired… To Self-Destruct.
