Sixteen year old singer Justin Bieber walked smack into the glass of an automatic revolving door when trying to exit a German hotel, sending his fans into a blogging frenzy.
"Ouch! I just walked into that door ... my forehead hurts ... I walked right into the window," Bieber told a local broadcast team that captured the incident on camera as he was exiting the Radisson Blu hotel in Frankfurt.
Bieber can be seen in the video trying to push the automatic door, then turning to walk out, but instead smacking his forehead against the glass.
