Breast-feeding, dieting and exercise helped shed 57-pound baby weight, says Beyonce

The 31-year-old singer, who flexes her muscles in a belly-baring bikini and cropped sweater with hot pants in the magazine, told the New York Daily News that breast-feeding took care of the first 30 pounds.

She said that she was amazed at how the weight just fell off of her, but had to work hard to lose last 25 pounds, as a show was scheduled just three months after she gave birth to her daughter Blue Ivy.

She explained that she lost the weight by dieting and exercising, crediting a low calorie diet and rigorous dance workouts for her slim physique.

She said that when she puts on workout clothes and runs on a treadmill, she gets bored, adding that the rehearsals leading up to a tour always get her in shape.
