This was clearly a very emotional experience for Justin Bieber and for the audience. Okay, and for us. Throughout the entire performance, Justin’s dancing was on point as ever, whipping out the most incredible moves. In fact, he was pushing himself so hard, physically, that at one or two points, you could hear that he was out of breath, which definitely proves he was singing 100% live, no lip synching whatsoever.
