"I already put my makeup on twice today: I put it on to take my kid to school, and then I went home, washed my face, and put it on again to have lunch with you," she reveals to her interviewer. "I like to make my husband like me more," she says, laughing, "and he likes it when I'm wearing makeup."

Gwen says that while she finds it "ridiculous" to keep being asked about her secret to six-pack abs, she offers up tips but confesses she really doesn't have a magic formula. "There is no secret: You just have to eat healthy, work out, and torture yourself!" She adds that jumping around onstage for a few hours for thousands of screaming fans is great cardio, and she also hits the gym when her hectic mother-of-two schedule allows.
