When Jennifer Lopez takes the stage at Sunday’s American Music Awards it will be her first live performance before an audience, such as the AMA’s, live in some time. Rehearsing for the anticipated performance, which also serves as the debut of her new single “Louboutins,” Lopez said “I think it’s going to be good”. “Dancing again, singing, the lights and the costumes — it all feels like second nature,” Lopez told press during rehearsals. As previously reported, Lopez joins a stellar line up that includes Janet Jackson, Whitney Houston, Rihanna, Adam Lambert, Mary J. Blige, Alicia Keys, Jay Z, Daughtry, The Black Eyed Peas, Eminem, Green Day, Lady Gaga, Carrie Underwood and Keith Urban. Catch the 37th Annual American Music Awards on ABC, Sunday, November 22 at 8pm.
