At the 2015 American Music Awards, Justin Bieber rocked a Nirvana shirt that upset, well, Nirvana fans. The question became... Does this pop dude even like the iconic '90s band? According to Courtney Love, he's cool, and in a recent interview with Esquire, Biebs' stylist Karla Welch further confirmed that, doy, Justin loves Kurt.

The interviewing asks about the shirt, to which Welch responds,

"Actually, it’s not the first time he’s worn a Nirvana tee. We just have a nice collection of vintage tees, and then the tee he wore yesterday was actually Jerry Lorenzo’s from Fear of God. Jerry takes vintage tees and re-cuts them. But yeah, of course he’s a fan of Nirvana. I think it’s so funny that all these people are up in arms. I’m sure Kurt Cobain would be like—I mean I can’t speak for him, obviously—but I don’t think he was so snotty or that he would diss anyone who appreciated his music. I think he understood that that is like the antithesis of music appreciation. It’s so funny. But you know, fans are fans!"

There you have it, folks! Biebs loves grunge. But you probably already knew that, right? If so, take our ultimate fan quiz and test your knowledge of the guy!
