Lopez, Lambert acts top tonight’s AMA show

Jennifer Lopez plans to include fireworks and an on-stage costume change in tonight’s American Music Awards performance.

“American Idol” runner-up Adam Lambert will incorporate leather and chains into his.

Lopez is set to perform “Louboutins,” the first single from her new album, “Love?,” due in stores next year.

Flanked by back-up dancers, the 40-year-old entertainer busts out her Fly Girl moves in a number that begins in a boxing ring and ends in the audience. Famed sports announcer Michael Buffer is in the act, too.

Lambert, 27, said he’s eager to see how the star-studded crowd responds to his provocative performance, a sexed-up rendition of “For Your Entertainment,” the first single off his upcoming album of the same name.

The performance is heavy on leather and chains and includes Lambert dragging a woman across the stage.

Other artists set to perform at the 37th annual awards ceremony include Rihanna, Whitney Houston, Green Day, Lil’ Wayne, Lady Gaga, Eminem, Keith Urban, Jay-Z and Carrie Underwood.

Janet Jackson will open the show with a medley of songs, but producer Larry Klein wouldn’t say whether her performance would be a tribute to her late brother.

“It’s a surprise,” he said.

Fans voted online to choose the winners of the American Music Awards, which honor the year’s top-selling artists in eight popular genres.
