Justin Bieber just canceled the rest of his “Purpose World Tour” and while some fans are upset about it, John Mayer thinks he probably made the right decision, and defended the move on Twitter.
“When someone pulls remaining dates of a tour, it means they would have done real damage to themselves if they kept going," he tweeted. "We've lost so many great artists lately. I give Justin [thumbs up] for realizing it was time to call it. You should too."
