Justin Bieber goes shopping wearing a gas mask Wed-27-Feb-13 13:16 Justin Bieber was snapped yesterday (26/02/13) in London shopping wearing a gas mask! Whyyyyyy you ask? We're wondering why too. Biebs did post a pic of him wearing the Darth Vader-esque headgear on Instagram but didn't shed much light on it apart from something about being "the best" or something. Maybe The Biebs is channeling Lady Gaga's eccentric fashions? Maybe he's dipping in popularity polls and wants more attention with a crazy stunt? Or maybe he just can't handle all that english air and needs it filtered on demand... Odd Bieber, very odd.
