I saw her in 2012 with Dance Again World Tour and she's and incredible live performer. Obviously she's not the best vocalist but she doesn't do lipsync as some of ignorants people that have never seen her live are commenting on here. She can hold her notes and dance like a beast at the same time. At that time I payed the half of what Femme Fatale Tour costed me and JLo deliver is without a doubt waaay much better than Britney's.
