NHL teams have an unwritten rule that no one may stand on the logos in their locker rooms. Not even Justin Bieber. But the Biebs—no stranger to disrespectful acts—was caught doing just that in the Chicago Blackhawks locker room before a concert earlier this month. The Boston Bruins did not want to risk the same fate, reports ESPN. So before the star played TD Garden last night, the team Bieber-proofed its logo, roping off the area so his oversized teenage sneakers could not clomp all over the sacred piece of carpet.
