Justin Bieber unwittingly committed a hockey no-no by standing on the Chicago Blackhawks' logo in their dressing room at the United Center, where he performed Tuesday night. The 19-year-old Bieber, from Canada and a known hockey fan, was posing for pictures with the Stanley Cup, which the Blackhawks won on June 24. There was also a personalized Blackhawks jersey with Bieber's name on it in the background. But what upset some Blackhawks fans on Twitter was a picture of the teen pop star standing on the team's Indian head logo while he was taking his own picture of the Cup.
