Valerie says she was extremely nervous before the shoot. "If I must be honest, it was torture. I just felt naked," she says. "But I think sometimes you've just got to feel the fear and do it anyway."

To get her size 6 body in top form for her bikini debut, Valerie says she amped up the exercise. "I've got this old-school workout—push-ups, sit-ups, tricep dips. And it worked," she says. "Anybody can do this at home."
