Despite being out of tune as most of the times in her case and having such a damaged voice which she can not control (nerver could really), it was a great performance, it was entertaining and she do choreo. Definitely better seeing Xtina Aguilera than bores Ariana and Nicki Minaj. If I have to choose a Mariah Carey clone (except none of them could came close) I think I´d choose Xtina. She showed the more artistry among them in her albums and is the best performer among them too.
