Cleveland Cavaliers fans are not going to be happy when they read this article.

Justin Bieber, who is known for putting curses on teams when he predicts they’ll win or roots for them (Conor McGregor, Clippers last season), rocked a LeBron James jersey during his Purpose Tour which stopped in Cleveland on Tuesday night.

Bieber also said he thinks the Cavs can win a title, which means they probably won’t.

Anyway, here’s a video of him putting on the jersey, much to the chagrin of Cavs fans.

Sorry, Cavs fans, but the “Bieber Curse” is almost as strong as the “Kardashian Curse,” and will be tough to overcome.
