The 2013 American Music Awards will air live from L.A. on Sunday, November 24th at 8pm on ABC. Already announced to take the stage were Justin Timberlake, Lady Gaga, Macklemore & Ryan Lewis, Miley Cyrus, Kendrick Lamar, Luke Bryan, Florida Georgia Line, Ke$ha, Imagine Dragons, One Direction and Pitbull, and now three more huge acts have been added to the lineup. TLC (along with “a special unannounced guest”…Lil Mama?), Jennifer Lopez (who will perform a tribute to Celia Cruz) and Katy Perry (opening the show with her new single “Unconditionally”) will all be hitting the stage as well. Sounds like it’s going to be a really good show this year! Will you be tuning in?
