Brooke's Secret To Keeping Love Alive: Sex It Up!

Dancing with the Stars' Brooke Burke Charvet juggles four young kids and a hectic schedule, but she never lets her new husband, David Charvet, get lost in the shuffle!

"She knows the importance of looking sexy and fit for her hubby!" says a source. "She works hard at being a good wife."

"But Brooke put her foot down. She and David insisted the girls be banished to their rooms, so they could spice up their sex life…and it worked!"
