While Bieber didn't directly address the photo, he went on to comment on his constant critics. "2013 ... new challenges. new doubters...Im ready. We are ready. see u all tomorrow and everyday after that," he wrote.

This was a rocky end to an already rough week for Bieber as a paparazzi attempting to get a photo of him was killed by a passing car. "While I was not present nor directly involved with this tragic accident, my thoughts and prayers are with the family of the victim," he said in a statement. "Hopefully this tragedy will finally inspire meaningful legislation and whatever other necessary steps to protect the lives and safety of celebrities, police officers, innocent public bystanders, and the photographers themselves."
