6 – Britney Spears
“Hit me baby one more time!” One of the biggest celebrities and music icons on our list, Britney Spears joins the ranks of child stars after launching her career at just eight years old alongside Christina Aguilera, Justin Timberlake and Ryan Gosling on The Mickey Mouse Club.
It wasn’t long before the 18-year-old Spears released her smash album …Baby One More Time only to follow it up with hit albums like Oops! I Did It Again and Blackout.
Perhaps one of the most public meltdowns on our list, the Princess of Pop’s music career came to a complete halt in 2007 after she entered a drug rehab clinic just weeks after her aunt died of cancer.
Spending less than a day in the center before leaving, Spears had one of the most famous tabloid shots in media history when she walked into a salon and shaved her head. Soon after, Spears returned to rehab and has managed to make it through a very public rough patch only to establish herself once again as a star.
