11. Britney Spears
The princess of pop was only a teenager when she first went under the knife for a breast augmentation that she later removed. These days, it appears that Spears has gone back under, but for different body parts. It???s likely that she had a nose job resulting in a thinner nose, and also bought some new breasts, but smaller than her first enhancement. Before and after photos suggest that Spears may have had even more work done than what is obvious, but she???s not telling!
