Although Justin Bieber doesn't turn 22 until tomorrow, that didn't stop the singer from celebrating a little early! Justin had a star-studded party that of course included a photo booth and tons of fun pics. Stars like Kylie Jenner, Hayes Grier and Joe Jonas — who just so happens to be going out on tour with JB's ex, Selena Gomez — were on hand to help the "Love Yourself" singer celebrate his special day. And it looks like everyone had such a great time!
