Britney Spears has undergone a body transformation — Whooa!
Look at these before and after pictures posted online by her trainer Derek DeGrazio.
The femme fatale’s entire body has trimmed down dramatically in just a few months.
She’s lost weight and gained muscle.
In fact, if we didn’t know better we’d think the picture was Photoshopped?
Derek, who has taken a nine month leave of absence from Barry’s Bootcamp in West Hollywood, is touring with Britney and working out with her every day and keeping tabs on her nutrition.
Her workouts are a variation of the boot camp class: 30 minutes on the treadmill and 30 minutes of floor work with weights and bands and bars.
Looking good Brit!
