Cant seem to lose stubborn belly fat, how can i?

First, some thing you need to know: I'm a bodybuilder. I have a lot of muscle on my frame. I eat right usually, though i cheat every now and then and eat pizza, etc. i work out regularly and am very active. I dont have much belly fat, you can still see my abs clearly. but i have this stubborn patch on the lower belly that wont go away. suggestions? thanks
