Joanne Stefani Germanotta aka Lady GaGa looks more like a robot than a pop star, as she arrives back at her London hotel just after 1.30am, having performed at the 02 Arena earlier in the evening. GaGa was wearing ripped fishnet stockings, a black visor shaped mask across her face and forehead, and a small video camera mounted on her red and black outfit, which she held in place to finish off the bizarre look! London, England.
