Metallica fans weren't happy with Laverne Cox's during the Grammys on Sunday night.

The "Doubt" star, who broke out into fame on Netflix's "Orange Is the New Black," completely forgot to introduce the iconic heavy metal band while she was supposed to be doing just that. Instead, she only name dropped Lady Gaga, who helped frontman James Hetfield sing the band's single "Moth Into Flame."

“Ladies and gentlemen, all my gender non-binary people watching tonight, eight-time Grammy award winners and six-time Grammy winner, Lady Gaga,” Cox said.

To make matters worse for fans who tuned into the CBS broadcast to see Metallica perform, the performance was marred by a major technical difficulty: Hetfield's mic wasn't working.
