As we told you earlier, the American Music Awards took place last night and it was a night packed full of stars! No big surprise who the biggest star of them all was though - Justin Bieber took away several prizes and also won the big one - "artist of the year"! Congratz Justin!There were also some amazing live performances including the huge stage comebacks for boy bands New Kids on the Block and the Backstreet Boys! There were more than 12 live acts in one night! Wow! Here are some pictures of some of them. Enjoy!
