Having three kids hasn't slowed down the career of model and "Rock Star" host, Brooke Burke. The All-American cover girl credits her post-pregnancy abs and hourglass shape to stretching and core-strengthening Pilates workouts and tummy wraps.

Now pregnant with her fourth baby, Burke says she's been doing Pilates for eight years. "It supports your back and I think it helps for an easier delivery."

Burke quickly shed the 30 pounds she put on with her last baby. She reveals that for 40 days after giving birth, she religiously wore an adjustable waist trimmer called 'Tauts Belly Wraps.'

"I didn't invent this. It's been around for thousands of years," she explains. "It creates some compression, helps your uterus go back down to its original size and it helps the tummy go back much quicker," Burke claims.

The actress also listed a number of her 'moms must-have's,' including the Bugaboo stroller –"I love the design and maneuverability," she says–as well as a swivel rocker with ottoman for breast-feeding, story time, and relaxation.
