Whoever cast the celebrity judges on The Voice sure knew what they were doing, didn’t they? When it comes to voices, no one can deny that the green ogre-friendly diva’s got one — and a mighty one, at that. Xtina demonstrated just that at Red Rock in Denver on Friday, belting out some of her most heartfelt (aka non-Bionic) hits — including “Beautiful,” “Ain’t No Other Man,” and “Lady Marmalade” — the last of which is another Xtina tune we don’t think should ever be Kidz Bop-ified. Watch the performances below.
And hey! She remembered all the words!
