biebersnl3 Blizzard or not, Justin Bieber is having one hell of a Saturday! He acted as host and performer on tonight's episode of Saturday Night Live. Wearing his signature Zack Attack-esque hairstyle, a leather jacket and jeans, a somber Justin performed the slow song with power and emotion. It was evident that he was singing about his ex-girlfriend, Selena Gomez, who recently broke up with him for the second time. Watch Bieber go to work http://youtu.be/EmpStME0YEk Sing it Justin!
