Lady Gaga's Glowing, Fibre-Optic Disney Princess Wig

Lady Gaga's latest costume is a very cool wig made out of real human hair and "the finest fibre optics in existence." She and her wig maker drew their inspiration for these glowing blonde locks from the idea of a "Disney Princess going to a rave." Of course.

The fibre optics are attached at the root to the wig's scalp, and the whole the plugs into a generator that can be controlled by Gaga's lighting supervisor when she's on stage.

One question remains: When did she develop a British accent? [PSFK]
