Lest we forget ... Justin Bieber's had QUIET a hiatus. He cancelled the remaining dates on his Purpose tour back in the summer of 2017 and he hasn't really worked since. Yes, he recorded a few tracks and made some appearances, but he's had some serious time off. And that's a good thing! He admitted to the world he needed to focus on himself and on his mental health. And oh, he got married!

That said, now he's back to work and Justin is one of the hardest working people in show business! When we caught up with him the other day at the rehearsal studio, he looked completely exhausted after yet another day of physical practice. JB has been putting in a lot of time recording and working on his moves ahead of his big tour and upcoming album. And it looks like he's lost quite a bit of weight. Is the hectic schedule getting to him?
