I don't know why, but certain metal fans get very upset when Justin Bieber wears a Metallica shirt. But it happens so often now, what does it even matter? Metallica's James Hetfield even joked about it in his top 10 things of 2015.
It's clear Team 'tallica sent Biebs a care package of shirts, because he's been rocking different Metallica shirts each time he's photographed in one. Above, is a still I caught watching the Grammys tonight when they were hyping Justin Bieber's performance. Bieber didn't wear the shirt during his actual performance, but was spotted in the shirt during multiple "coming up next" spots with footage of his rehearsal from earlier in the day being shown. That is where the still above comes from.
But ultimately, who cares if a pop star is wearing a Metallica shirt? How does it affect your enjoyment of the band? It doesn't. Best case scenario, a Bieber fan actually puts on Metallica, likes it and becomes a metalhead for life.
As for actual metal at the Grammys, Ghost picked up the Best Metal Performance Grammy. Video of them walking the aisles for their acceptance speech is amazing.
