Britney Spears started out as a squeaky clean Mouseketeer, but after splits from Justin Timberlake and Kevin Federline, Spears had a breakdown in 2007. The singer infamously shaved her head, was rumored to have drug problems and was put under a conservatorship that still stands today. Thankfully, she’s eliminated the “Toxic” people from her life and is enjoying living with her sons and her Vegas residency. (Photo by Getty Images/Bauer-Griffin)
