Christina Aguilera Performs At Michael Jackson Tribute Concert (PHOTOS)

Christina Aguilera paid tribute to the late King of Pop, Michael Jackson, in concert in Wales on Saturday.

Taking the stage in a a skin-tight bodysuit and tights, the 30-year-old singer followed the celebrity trend of shunning pants that's been popular for the last few years.

With clownish makeup and bleach blonde extensions looking ratty and tangled, the singer's appearance shocked the audience as she performed Charlie Chaplin's "Smile."

For her second set the singer changed into a more flattering outfit, but still didn't look quite like the songstress fans are used to seeing.
