Christina Aguilera reportedly shocked fans and horrified parents with her live show at London's Royal Albert Hall.

Amongst those shielding their eyes was US Secretary of State Colin Powell, who, like many others, was unprepared for the pornographic performance.

A video clip of the star writing almost naked on a sun lounger set the scene, before Christina belted her way on stage in a leopard print swimming costume and let dancers spank her with giant feathers.  

A guest tells the Mirror, "People were outraged and were covering their children's eyes. It was like porn."
