Our national music hero just lost a few points in his fans' respect again.
After sweet public appearances in nightclubs and bars, and accepting his AMAs, it seemed Bieber had found peace after all.

For some reason, the man reached out to Bieber through his open window. Biebs apparently got scared, and took a swing at the man's face, who ended up with a bloody mouth to remember the night from.
