Was this the first Katy Perry performance y'all watched?
If not you should realise that she has clearly been working on her dance moves, I was quite impressed by how far she has come, personally.
The purple hair's brilliant, but her vocals on all parts except the middle-8 were bad. Decent enough performance, probably the best of Part of Me, but still no excuse for not doing Dressin' Up/Wide Awake.
(I know I said I wasn't going to watch, but I had to do something whilst waiting on The Little Mermaid steam to load!
)
Best PoM performance ever. 
Her performance skills. 
And also very HOT!
