Does Ronnie, Sammi, Snooki, Vinny, and Angelina of "Jersey Shore" have a Facebook?

Where can I find the Facebook fan pages for Ronnie (Ortiz-Magro), Snooki (Nicole Polizzi), Sammi "Sweetheart" Giancola, Vinny (Guadagnino), and Angelina (Pivarnick)? I am looking for "official" pages/profiles-- fan pages these people have made, not other people. Can't stand posers/imposters. Please include links/urls if you know, w/ your answer.
