I don't think problem was the choreo, I feel its J.lo, she was extremely nervous plus she didn't rehearse enough, she was in new york this past week nd u can tell frm her movement, she even made a couple of mistakes, I feel the bma performance wld be better becos she'll hv a bigger stage nd the camera wld b focusd on her, not zooming off whenevr she abt to twerk! Fearing she wld do some obscene kinda dance like they did on idol!
Singing live and dancing is a completely new territory for JLo. I feel like she was more focused on delivering best vocals possible than dancing. I for that. She really has grown a lot as a performer.
