Suffers From: Achluophobia (fear of the dark)

Christina Aguilera has a well-documented history with being a diva. So it's probably best not to anger her, like turning off the lights and yelling 'Boo!' would. It would definitely set the 'Your Body' singer off, since Xtina's totally afraid of the dark!

She once said, "In the big picture I'm pretty fearless, but I am afraid of the dark. I sleep with the light on. Or the TV. It's comforting. I wasn't scared of the dark as a child. But as I got older and started spending time in hotel rooms, it was a comfort to keep the TV on so that you felt that you were not so alone."

So there ya go, every demanding diva has a weakness. Christina's happens to be sleeping with a nightlight, hopefully a 'Genie in a Bottle'-inspired illuminator.
