Christina Aguilera is Kaleidoscope Cute

Christina Aguilera works out a crazy Pucci kaleidoscope-like top and purple YSL platforms at the Africa Rising Festival in London on Tuesday night.

Tonight, the 27-year-old singer will perform at UK’s Royal Albert Hall for the ThisDay-sponsored event. Christina will be sharing the stage with the likes of Seal, Youssou N’Dour and former U.S. Secretary of State Colin Powell.

The event will also feature catwalk shows from international designers and models including Naomi Campbell, Alek Wek and Tyson Beckford.
