Model and TV "Rock Star" host BROOKE BURKE is famous for her all-American-girl looks and bikini photos. Now after three children, the cover girl is sharing how she keeps her flat abs and hourglass shape with our own THEA ANDREWS, who is also pregnant. Brooke's secret? Stretching and core-strengthening Pilates workouts along with post-baby tummy wraps!

"I've been doing Pilates for eight years," says Brooke, who is now pregnant with her fourth baby. "It supports your back and I think it helps for an easier delivery."

Like most women, Brooke says she gained 30 pounds with her last baby. But she soon had her bikini-ready belly back in shape. She credits her recovery to "Tauts Belly Wraps," an adjustable velcro waist hugger that she wore religiously for 40 days after giving birth.

"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."

Tauts Belly Wraps are now available for sale on Brooke's Web Site, Baboosh Baby.com.
