Tummy Pooch problem. Please help.?

I'm not fat , at all. I'm 5'4 , I have an athletic build and I'm 107 pounds. The weight doesn't bother me. What bothers me is the tummy pooch I have. I am wanting to be a model / actress/singer and I need to get rid of it. I have been working out for about an hour a day on Wii fit using ALL of the tummy workouts , for two days. I'm eating healthier , smaller amounts , slowly and stopping hwen Im full , I'm drinking plenty of water , and I limit myself to 15 minutes computer time. If you know any thing else , tips or excersizes I would appreciate it! Thanks so much <3
