Get ready for another epic Katy Perry awards show performance, Katycats!

Perry has been given the honor of opening the American Music Awards, airing live from the Nokia Theatre in Los Angeles on Nov. 24. She will deliver 'Unconditionally,' the second single from her new album, 'Prism.' Tune in to see how it will compare to her sparkling performance of the same tune at last weekend's (Nov. 10) MTV Europe Music Awards.

Newly joining Katy on the bill are Jennifer Lopez, who will be paying tribute to legendary salsa singer Celia Cruz, and TLC, who are making their return to the AMAs stage with a special surprise guest.

Previously announced performers include Miley Cyrus, Lady Gaga, Imagine Dragons, Kendrick Lamar, Macklemore & Ryan Lewis, One Direction and Justin Timberlake. This year's AMA host, Pitbull, is also scheduled to perform.

With six nods, Macklemore & Ryan Lewis lead the nominations for this year's fan-voted awards. Taylor Swift and Timberlake follow with five nominations each.

The 2013 American Music Awards air Nov. 24 at 8PM ET on ABC. The preshow -- which features Lance Bass, Jordin Sparks, Colbie Caillat and more -- will stream online starting at 5PM at several outlets, including here.
