Justin Bieber isn't 100% sure how he even arrived at a stranger's house party in South London. Soon he never wants to leave. All because Moses asks the question on everybody's lips: "So why you been acting like such a fucking wanker?" Of course he doesn't know the answer to this all important question, because all he does know is that he's famous, he's confused, he's a little bit very drunk and he misses Kelly. He misses Kelly a lot.
