How to get rid of cellulite?

Im 14 and have terrible cellulite. I am thin, and eat pretty healthy, and I still have disgusting cellulite on my butt/upper thighs, all over legs, and just recently I've noticed on my stomach. I feel very self conscious and I want to ferris of it before summer. What are cheap ways to get rid of cellulite? And exercises would be awesome! Thanks!
