There's no context or explanation, so maybe Bieber was just expressing his support for the Cavaliers prior to Game 2.

But we didn't forget about Bieber's attire just a few months ago, when he wore a full Steph Curry Golden State Warriors uniform to play pick-up basketball.

It's not too late to say sorry, Justin.
