Baby, baby, baby, oh, did Justin Bieber have a big night at the American Music Awards! The tween sensation picked up three awards during the evening (and a fourth off-air), including the night’s biggest honor: Artist of the Year. (Fun fact: Bieber is officially the youngest to take home the top prize.) And though he dedicated his first two awards to God and Michael Jackson, he saved the third win for his mentor — taking the stage for his acceptance speech, Bieber said, “You know, I really got this opportunity really about a year-and-a-half ago, and really was embraced by a man named Usher Raymond. And I don’t know, but I feel like he’s had such an amazing ride, and it would only be right if I invited up here to share this with me. Not only my mentor, but my best friend and my big brother. I love you man.”
