Hollywood Post-Baby bodies

Hollywood’s new moms share the diet and exercise secrets that got them red carpet ready.

KATE HUDSON

A devotee of the Tracy Anderson Method, the Something Borrowed star revealed her white-hot bikini body in France just seven weeks after the July 9 arrival of baby Bingham. By November, Hudson, 32, had danced herself back into tip-top shape, rocking a daring black Stella McCartney cutout gown at the British Fashion Awards.

BEYONCÉ

Wearing a hip-hugging orange Alice by Temperley dress and a pair of towering Christian Louboutins, the superstar flaunted her enviable-as-ever figure in N.Y.C. just one month after welcoming daughter Blue Ivy Carter at husband Jay-Z’s Carnegie Hall concert. Her secret? Breast-feeding, 90-minute workouts three times a week and a strict protein-based diet.

JESSICA ALBA

The dedicated second-time mom slimmed down with a 1,200-calories-a-day meal-delivery diet and daily gym sessions after the Aug. 13 birth of daughter Haven. Three months later, the 30-year-old star showed off the stunning results with a chic red carpet reveal at the Armani Hotel Milano. “Working out every day for even just 45 minutes is good for my mental state,” she told Lucky magazine.

MIRANDA KERR

Eating a healthy diet rich in fish and salad during her pregnancy helped the Australian supermodel get bikini ready fast after the Jan. 6 birth of baby Flynn. The body-confident new mom debuted her flat tummy just three months later during her first post-baby bikini shoot.

MARIAH CAREY

The superstar mom admitted she tipped the scales at “a number that I never want to see again” by the end of her tough pregnancy with twins Moroccan and Monroe. Unable to exercise for several weeks after her April 30 C-section, the Grammy winner turned to the Jenny diet plan. “The first week, I lost 40 lbs. … of just water,” she told Rosie O’Donnell in November, revealing a slim physique and 70 lb.-weight loss.
