However, Spears isn’t alone in blossoming into a sexy star.
The 30-year-old actress was spotted showing off her healthy physique in a blue bikini on a yacht in Italy in 2007. But since then, the actress has lost a significant amount of weight in order to step into the famous role.
Hathaway hasn’t been shy about the extreme measures she took to lose 25 pounds for the role of Fantine.
She told Vogue magazine that she had been living off of “two thin squares of dried oatmeal paste per day.”
Extreme measures aside, Hathaway and the rest of the Disney crew do know how to rock a bikini.
