As far as the whole music/performance presentation is concerned, it was simply amazing (and blushingly dirty). It was bright, colorful, fun, enthralling and the singing was great too. What a concept!!! As far as outfits, my favorite would have to be her angelic fairy outfit. I don't know how she did it, but her dress/headgear moved and she spread wings and just...it just had to be seen to be believed. Favorite performance of the night was "Paparazzi" when she slayed a large "Fame Monster" fish on stage with flashing lights from cameras and a sparking bra (seen to believe again). However, all of her performances were great and powerful.
