Justin Bieber single-handedly ruined Christmas for his fans with just 44 characters:

There's the strong probability the Toronto superstar was just joking about quitting, however. Last week, Bieber told Los Angeles radio station Power 106 he was retiring before telling TMZ he was only kidding. He also told USA Today in an email how he was planning on spending his time next year. "I'm going to take my time (next year) to really find my sound as an adult," it says. "That takes time and patience, and I'm grateful I have the ability to step back and focus on my creativity." The singer may be just referring to temporary retirement on the tweet.
