A few weeks ago, Justin Bieber was roundly mocked by the Internet for getting carried up the Great Wall of China by his bodyguards. It probably will not change anyone’s opinion on the matter, but here is some explanation: Justin Bieber was there filming a “guerrilla” video for his new song, “All That Matters.” (He’s just giving away songs now, in the hope that you will like him again.) Maybe union rules say Justin Bieber has to be carried places when he’s filming? No? Okay.
