Like many brides-to-be, Vanessa Minnillo is stepping up her fitness game before the big day. The star, who became engaged to Nick Lachey in November, has been working out three times a week with celeb trainer Gunnar Peterson. At a recent Under Armour event for its new Charged Cotton activewear, Vanessa told InTouch Weekly that she and Gunnar have been working out hard and that he trains her "like an athlete." She's still eating the kinds of food she wants, like pizza, but practicing portion control. Most of all it seems like Vanessa has a healthy attitude: "I am happy with where my body is now. I am happy in general, and I think it's all connected."
