Meet Jersey Shore's Newest "Guidette"

Look out Seaside Heights, Jersey Shore's got a new "guidette" on the loose, 22-year-old Deena Nicole Cortese, better known as Snooki's best friend.

Cortese, who describes herself as "class in a glass and party in a body", origninally auditioned for the first season, but lost out to her best friend. But now she's back, raising hell and cleaning house in Seaside Heights.

But even though Cortese seems ready to bring on the drama, her BFF Snooki may be pulling back a little. After her recent arrest for disorderly conduct, Snooki says's she's going to stop drinking -- well, during the day at least.

"I just felt really bad, so I'm definitely going to stop drinking during the daytime. And now when I go out, I only have a couple drinks," Snooki recently said.

And Snookers seemed appropriately subdued as she and the rest of the cast were at LAX, heading back to Jersey after a brief trip to LA.
