After a concert in Birmingham last night, Justin Bieber arrived at his London hotel at 3 a.m. on the morning of his 19th birthday. He then darted around the wintry streets in a state of partial nudity. At first sight, I thought his abs might be airbrushed. (Necessary, perhaps, for the concert?) Upon zooming in, however, I remain open to the theory that he had been seated in a slouched position before this photo was taken, and those red lines are creases.
