Best performance among all! I loved Beyoncé but it wasn't great! Jennier Lopez as I already said a million times hasn't the best voice in the world, she isn't a perfect singer but nobody can say a thing when it comes to enterteinement. People love to see J.Lo on stage! She knows how to keep people with energy. She's the greateast performancer. I think she's best than Madonna, 'cause Madonna doesn't dance like her and Madonna hasn't a great voice either. Madonna isn't really about music but behavior and stuff like this. Jennifer has my respect. She isn't a perfect singer but people love her because she's hot and she has "The Thing". Many girls like Rihanna, Kety Perry and other young singers of this generation can't do what she does, this is the real true and YOU ALL know that! Haters don't answer please 'cause you're going to act like those crazy stupid Rihanna fans, that I can't stand... XOXO, call me maybe!
