And we are live from the Nokia Theatre in LA for the 40th annual American Music Awards. Our host tonight is... no one! Instead of hit & miss chit chat from some late show host, the AMAs are instead concentrating on the music, featuring performances by the likes of Justin Bieber, Carly Rae Jepsen, Nicki Minaj, Christina Aguilera, Usher, Taylor Swift and Ke$ha, among many others. And in addition to the awards, look for a tribute to AMA founder Dick Clark who passed away this past April at age 82. Let's get started!
