Videos - Christina Performs 'Lady Marmalade' & 'Beautiful' In Denver

These are the first videos of Christina performing for Mircosoft in Denver. They are LQ, but that's to be expected.

Her voice on 'Beautiful' sounds epic! (that's the only one I've heard so far)

I love how Christina shouts "You know this!" When she's apart to perform 'Lady Marmalade' so cute!
