Bullying isn't cool, guys. Seriously. And look what you went and made poor Justin Bieber do because of all your teasing.

Bieber debuted his bleached dreadlocks look last month, and ever since everyone's been making fun of him because of them — even his fans. Bieber even took to Instagram last week to complain about all the backlash. "'Dude, are you gonna do anything with your hair or are you just gonna leave it like that, dude?' Yeah, some girl came up to me, like, 'I love you Justin, but like, that's like my least favorite of yours,'" he said in the video.

But apparently all the criticism finally got to him, as he debuted a new buzzed head this weekend, along with several photos of him refusing to smile.

Aw, poor guy. His fans, by the way, are thrilled — at least according to their comments.
