Neck Flab!

Does anyone have any tips for getting rid of the extra neck/jaw area flab?

I gained quite a bit of weight while pregnant and one of the places was there, I don't mind the extra weight everywhere else but I just can't stand it in that spot. Will working out regularly and eating a healthier diet help that shrink some? Or is there anything specific I can do to help it? Or is that area just one that is stuck like that mostly?
