Christina Aguilera performed at the 2008 American Music Awards. Aguilera sang in a black dress and then stripped down to her bare essentials. Aguilera has taken up the corset as a part of her stage wardrobe. She rocked in her naughty looking lingerie. Aguilera kept the fire going with “Beautiful”, “Keeps Getting Better”, “Dirrty”, “Fighter” and “Genie in a Bottle”. She has made a successful post-pregnancy comeback. How do you like her new look?
