KPs performance was good! Not her best, but I liked it. I feel like the sound wasn't correct in the beginning, then it got normal. I guess their was audio issues? Live wise, KP was my second favorite. I thought Bruno Mars was amazing live. I don't like his music much, but I give the guy props. He sounds amazing live every time. Justin T performance was ok. He hardly sang lol. Im not for all that dancing junk. I want SINGING! Mileys performance im my opinion was not bad. I mean yeah she went a little wild, but she doesn't have to stay stuck in Disney forever. People need to get that. She isn't 10 anymore lol As for Gagas performance, I thought her vocals were rocky at first, then got better. As for the "show" she put on, I was not impressed. That whole getting dressed on stage is a carbon copy of KP and Madonna, so I don't give any points to someone that copys... overall, no one was horrible. Wish I could have gone to see KP live!
