In this week's magazine, Alex Morris goes inside the bubble with Justin Bieber, and sees it all: the down-and-dirty vocal warm-ups ("He snorts like a horse along the scales. Then he meows like a kitten"), the singular mania of the Beliebers ("“We’re sharing the same oxygen as Justin Bieber"), the fears and nightmares of Bieber himself ("I’m claustrophobic, really bad"). To supplement Morris's story, we here at Vulture have taken a look at another part of the Bieber phenomenon: his powerful, agile, often karate-like dancing. Doing our part to further the field of Bieberology, we've identified all 25 Bieber dance moves. Click and learn.
