JLO was definately lipsyncing on Fashion Rocks in '07, because if she could sing that well without help, why is she still lipsyncing now? I'm telling you JLO has all sorts of tricks and manuvers she uses (and is extremely good at) to try and fool the public into believing its a live performance.

It's funny. I remember when she performed her Spanish song Que Hiceste (sp) on American Idol where she HAD TO sing live. Her backup singershelped her carry that whole song., but if you didn't know any better it seemed she gave a totally live performance. lol!
