Met Gala Ball 2010 - Katy Perry.jpg

Always one step ahead of the crowd, Katy Perry quite literally lit up the red carpet at the MET Gala last night thanks to a specially designed gown made of LED lights. The popstar wasn't joined by her fiance, Russell Brand, but rather the designer of the CuteCircuit dress, who cleverly concealed tiny fairy lights beneath an off-the-shoulder white gown. The result was a dress that glowed neon colours as Katy made her way inside. Needless to say it was a talking point of the night.
