It’s time for another installment of everybody’s favorite game, Guess That Ass! This time we have a pretty nice, round ass provided by a singer/actress that everybody knows and most probably hate! Can you guess who owns this nice ass? Hit the jump to find out!

You’re right if you guess it was the ass that belongs to Hilary Duff! Hilary was getting into her car after doing some Pilates, and we can see that working out is really helping that booty. I’d work out at the same gym just so I could stand behind Hilary Duff and check that out. Thankfully the rest of her ain’t too bad either. I bet they couldn’t even gather enough evidence to consider me a stalker. I would only be in there everyday to work out; it’s just a coincidence I’m always directly behind Hilary Duff!
