Which Celeb Couple is Hiding Under These Masks?

One of Hollywood's hottest couples decided to shield their faces from the bitter cold NYC temps as well as from the paps.

Can you guess which prankster A-listers are hiding behind the old hag and monkey masks?

It's married couple Pete Wentz and  Ashlee Simpson-Wentz!

Pete and Ashlee stopped by a costume shop in downtown NYC today and left wearing masks.

The Wentz family is currently living in the Big Apple, supporting Ash in her role as Roxie Hart in the Broadway hit Chicago.
