Justin BieberThe unwritten fan rulebook states you can only pick one team and that you must stick with that team through its best and worst moments.

Someone needs to inform Justin Bieber of this. He apparently didn’t get the memo.

Over Bieber’s many years of being a music sensation, he has been caught wearing many NBA teams’ apparel. That leaves fans nationwide wondering who Bieber actually supports.

We can only imagine how many NFL, MLB or NHL teams he likes.
