Sporting a daring white bikini the 31-year-old singer shows off her toned abs and flaunts her iconic belly piercing.
During the interview Spears shared the exercising and dieting routine that keeps her looking fit and explained that she'll need to be in top shape for her upcoming Vegas gig.
“I’m doing 90 minutes of yoga twice a week in addition to a lot of cardio -- hour-long sessions three times a week with my trainer, Tony Martinez,” Spears told Shape. “The [Vegas] performances won’t be simple -- they’ll be a massive party from start to finish. And to pull this off, I have to be in top condition and running at full speed.”
Shape's June issue hits stands -- and tablets -- on May 20.
