Chicago Blackhawks to Justin Bieber -- We Forgive You For Being a Logo-Desecrating Dumbass

The Chicago Blackhawks aren't holding a grudge against Justin Bieber for trampling their beloved logo yesterday -- a crime punishable by death in some fan circles -- telling TMZ, Bieber didn't realize he was violating intergalactic hockey law.

In case you didn't know, Bieber -- who is supposed to be Canadian -- was taking pictures of the Stanley Cup in the Blackhawks locker room when he stood squarely on the team's hallowed Native American head logo.

FYI, not only is it a HUGE Blackhawks superstition not to step on the logo ... it's also an unwritten rule on any hockey team: never tread on the team logo.

But a rep for the Blackhawks says it's water under the bridge -- telling us, Bieber "did accidentally step on the logo but was immediately asked to step off and was extremely sorry as soon as he realized what he did."
