LOS ANGELES (AP) — Jennifer Lopez plans to include fireworks and an on-stage costume change in her performance at the American Music Awards. "American Idol" runner-up Adam Lambert will incorporate leather and chains into his.

Lopez is in top form, but she's still a little nervous. She'll be singing a song fans have never heard before and performing live on TV for the first time in years.

"You know what you're doing and you feel very good about it, but at the same time, you wouldn't be human if you're not afraid," she said. She's set to perform "Louboutins", the first single from her new album, "Love?"
