It was a bit rocky in the start, but it got so good towards the end. That was such a cool performance, considering it's her first time performing on live TV (I think? Well, at least performing her solo song when all of the eyes are locked on her) and she did so great. But the lyp-sincing was a bit too obvious because the contrast of her vocals when comparing verses to pre-choruses is just too damn obvious.
Overall, I loved it. It was so good. I can't get over the fact how cool, hot and amazing she is.
