How to get rid of cellulite?

I'm tall and almost have an hourglass figure. I've never been chubby or slightly overweight. I am super athletic (ballet , basket ball , gymnastics and I move a lot ) and I've always managed to keep my body at a perfect shape. But since I've started my senior year in college I've started to notice that I have cellulite on my behind and thighs (keeping in mind when I do gain weight it immediately shows on the parts I just mentioned) ! I need to get rid of it asap!! Any tips ?
