Big Booty, Small Waist?

Hey, ladies! I've been wanting to get a bigger butt, and I'm starting to exercise more. I have big love handles. But my waist is fairly small. And my butt is like negative space, haha. I was just wondering if anyone knew some specific foods and exercises to do for a bigger butt and no love handles. I can't do squats or lunges, because my knees give out easily sometimes. But any help would be great! Thanks!
