Next time you’re having a bad day just blame it on your workout routine.  That’s what Justin Bieber is doing these days.  The pope star is making headlines after a two week stretch including an out of control birthday celebration, showing up to his own concert two hours late and canceling one show completely.  He’s also been spotted lashing out at the paparazzi.  But he says it’s all because he’s been really busy at the gym and the photographers are picking on him.
