Something tells us Metallica won't be itching to perform at the GRAMMYs anytime soon.
The band's collaboration with Lady Gaga on Sunday didn't go exactly as planned, when frontman James Hetfield's mic was accidentally turned off. And now Laverne Cox is apologizing for accidentally leaving Metallica's name out of the introduction.
"I am so sorry to #Metallica and all their fans," Cox tweeted on Sunday. "I am told I didn't say their names during the intro. Love you Metallica. You Rock. #Grammys."

The 32-year-old Orange Is the New Black actress' intro mentioned "great bands," but failed to say Metallica's name.
"We all begin somewhere. Great bands usually begin in someone's garage or basement or some empty warehouse," Cox said. "And if they're really good, part of them always stays there. Ladies and gentlemen, and all my gender-non binary peeps watching tonight, eight-time GRAMMY Award winners and six-time GRAMMY Award winner, Lady Gaga!"

Mic problems then became apparent for multiple verses during Gaga and Metallica's rendition of the band's 2016 song, "Moth Into Flame," prompting Hetfield to move over to Gaga’s mic, which had been working. Hetfield, 53, appeared to be visibly upset after the performance, kicking down his mic stand and aggressively throwing down his guitar and his guitar pick.
