Pauly D's Not The Only 'Jersey' Castie Chillin' With Paris Hilton

Following last night's MTV Movie Awards, JWOWW and Snooki hit up Katy Perry's afterparty at John Terzian and Brian Toll's Las Palmas. There, the "Jersey Shore" girls partied it up with their new besties Nicky and Paris Hilton. They showed the A-lister sisters how to fist-pump, posed for pics with each other and then took to Twitter to share. (Does Pauly D know his roomies just hijacked his crush?)

+ What do you think about the new friendly foursome? Want to see more of the Jersey/Hilton fusion or are the "Shore" girls better off on their own? Sound off in the comments!
