Yesterday Lily Allen was exposed to be wearing Spanx when an empty packet was spotted in the back of her car. The singer is proud to be curvy and obviously wanted to look her best for the red carpet. I think we all know how important it is to look good to party.

Shaping underwear is a big industry particularly in recent years as TV presenters like Gok Wan and Trinny and Suzannah stress the power and importance of it. However, this got me wondering how often people actually wear spanx?
