If you can guess more than half of these before viewing the full sized image, you can consider yourself an Asspert. Yep, I definitely just made that word up so when you see it everywhere in 4-6 weeks, you'll know where it came from.

But anyway, check these pictures out. I had no idea some of these celebrity chicks had such killer rumps. Mmmm, I'm hungry.
