Jennifer Lopez is hard at work rehearsing her performance for the American Music Awards this Sunday. We'll be there covering the red carpet and big show, but here's a sneak peek at what to expect from J Lo. She'll be singing her new track, "Louboutins," wearing — what else? — a pair of Christian Louboutins designed especially for her.

Stay tuned for tons more coverage from the AMAs, but first listen to Jennifer Lopez's new song and let us know what you think about "Louboutins" — does it make you want to hit the dance floor or leave the club?
