Simply put, Justin Bieber owned the American Music Awards last night.
This 16-year old became the youngest singer to win Artist of the Year, adding that trophy to a haul that also included Pop/Rock Male, Breakthrough Artist and Album of the Year for "My World 2.0."
While on stage to accept the top honor, Bieber invited Usher to join him, referring to the R&B star as "not only my mentor but my best friend and my big brother." It was a very nice moment, only topped for many by Justin's rendition of "Pray," a single off his upcoming acoustic album

Other major winners at the AMAs included:
Lady Gaga for Pop/Rock Female; The Black Eyed Peas for Pop/Rock Group; Brad Paisley for Male Country Artist; Taylor Swift for Female Country Artist; and Carrie Underwood for Country Album of the Year.Gossip
