Justin Bieber hit the American Music Awards red carpet in a casual look that featured a Nirvana t-shirt – much to the dismay of diehard fans of the 90s grunge band.

Bieber decided not to suit up for the annual ceremony in Los Angeles Sunday, choosing to pair his Nirvana tribute tee with ripped jeans and white Vans. Though the look seemed harmless enough, many took to Twitter to slam the pop star for his attire.

Other red carpet looks at the 2015 American Music Awards proved to be less controversial – including that of Bieber’s on-again-off-again girlfriend Selena Gomez, who wore a red sequined dress for the evening.

Like Bieber, however, former No Doubt singer Gwen Stefani got some flack for her unique ensemble on the red carpet.
