Look guys... Beyonce performed for well over an hour... Singing, Dancing and god know what else... She performed fantastic and if she did seem tired a little bit or vocals were off on a note or 2... DONT YOU THINK THAT IT IS UNDERSTANDABLE DUE TO THE PERFORMANCE SHE WAS GIVING?!?! If you think you can do better without getting out of breath a tad then you would be on stage... BUT YOU ARE NOT... QUEEN B RULES AND HER PERFORMANCE WAS SIIIIIIICK!!!!
