It’s time for another edition of Guess That Ass! Now, the butt featured in the above photo today belongs to an “actress” that really has her ups and downs — and she just loves the Hollywood hills. She even had some Playboy audition photos floating around out there. Any guesses?

The posterior belongs to none other than Audrina Patridge! These photos were taken from the set of her new movie and Audrina was obviously cast for outstanding acting ability. Check out all the Audrina Patridge bikini photos from this set.
