Britney Spears does it again! Fourteen years later, the pop princess shows off her sexy abs ... but she's no longer a school girl with pigtails, this mother of two is proud of her post-baby bod, complete with tight abs!

Spears tells Women's Health the secret to her hot bod: "Dancing is a great cardio workout -- tough and fun at the same time." And just what does the superstar -- known for her love of Cheetos -- eat to keep the weight off? "I'm really into raw food -- sushi, basically." Her indulgence? Sweet tea! Just like a good, southern Louisiana girl.
