Jersey Shore

According to our sources, the cast hasn't been told the plan is to shoot season five right after they are done shooting four -- even though MTV announced it yesterday. We're told 495 Productions will break the news either today or tomorrow.

Our sources say the cast was originally told the next season of the show would shoot in August. As a result, we're told the cast members booked club appearances for July -- and those are HUGE money makers.

According to our sources, the cast will leave Italy in late June and go straight to Seaside Heights -- which is a problem ... since no one packed enough clothing.

MTV announced the season four premiere date of "Jersey Shore" on Friday -- and also their plans to start shooting season five later this month. That season, the cast will be back in their natural habitat of Seaside Heights, NJ.

We spoke with a rep for the New York State Department of Motor Vehicles ... who tells us, "Any accidents that occur in a foreign country do not affect a person’s driver license in New York State.”

As we previously reported, Snooki smashed into the side of a polizia squad car in Florence this weekend. She was taken into custody for questioning ... but not arrested.

Bottom line -- when Snooks returns to U.S. soil ... she'll be allowed to hit the streets again like nothing ever happened.

Snooki was driving when she struck the cop car, but sources connected with the production tell TMZ, "Zero alcohol was involved."

We're told no one was injured.

A witness tells TMZ, Snooki smacked right into the back of the patrol car, wedging her ride between the car and a highway protection wall. The witness says Deena was in the passenger seat at the time of the crash -- and when she tried to exit the car, she had to go through the window ... because the door was blocked by the wall.

Multiple sources close to both "Jersey Shore" stars tell us ... the guys had a long talk after the altercation and "worked out their issues."

We're told the whole fight went down in the first place after Ronnie had returned from a night of clubbing with his GF Sammi. Ronnie was pretty heated over an argument he had with Sammi ... and in his rage, "turned his anger towards Mike."

Sources tell us Ronnie began to talk smack to Sitch -- taking personal shots regarding Sitch's family -- and The Sitch eventually snapped.

The two men fought briefly before it was "quickly broken up" -- and Ronnie then blew off some steam by punching a wall and tearing up his knuckles.

As TMZ reported yesterday, Ronnie beat up The Situation the other day -- leaving Sitch with red marks all over his face and left eye.

The two arrived separately back to their apartment hours ago -- Situation has red marks covering his face around his left eye. Ronnie's knuckles were torn up and bleeding.

Details around the fight are still unclear -- but big surprise ... we're told it all began with a blowout between Ronnie and Sammi.

As TMZ first reported, The Sitch filed a lawsuit against his pops for that crazy website he created, TheConfrontationSite.com, claiming his dad is illegally using his name and likeness.

Frank got served legal papers while he was volunteering at a charity event in Delray Beach, FL -- which we posted a story about earlier this week, so we probably tipped The Situation off to his exact whereabouts.

The University of Florida sent out an email to students participating in their study abroad program in Italy -- which states "any student who does agree to participate in the filming of the show, or who signs a waiver or legal agreement of any sort with MTV, will be dismissed from the program immediately."

TMZ obtained the email -- warning the students that any action deemed potentially embarrassing to the school "will not be tolerated."

The school has also threatened to contact the student's parental units to inform them why the school would be kicking them to the curb.

Funny, we thought the U of F mascot was the Gator ... not the Rat.

UPDATE: The UF is now changing their tune ... TMZ spoke with Janine Sikes, UF Director of Public Affairs, who tells us, "Generally speaking, students may participate in activities outside their Study Abroad program as long as they meet the academic and living requirements of that program."

According to the suit filed Monday in federal court in Miami ... Mike Sorrentino claims his pop, Frank Sorrentino, is illegally using his name and likeness all over his website, TheConfrontationSite.com.

Mike also insists his dad is actively trying to damage his business reputation -- by posting anti-Situation videos and statements all over the site.

Mike also takes a shot at his father's business partner -- claiming the guy who created his dad's site is a scumbag businessman who has a long history of ripping people off.

Sources connected to la famiglia ... tell TMZ the Situation's lawyer sent the email to Frank Sorrentino -- aka The Confrontation -- warning of a lawsuit and an emergency injuction to shut down that website where Dad blasts Sitch.

Frank's rep says they're not taking down the website -- and they're not threatened -- especially since, he claims, the email referred to a "law suit."

It finally happened ... The Situation ... Pauly D ... Ronnie ... and Vinny have touched down in Florence, Italy less than an hour ago -- and were greeted with a crazy fan crush!

The Italian paparazzi went crazy -- snapping photos of the boys as they unloaded their bags out of a taxi ... and took their stuff into the building where they will be living.

We're told the guys had to cover the cab themselves -- and had to huddle up before they could figure out how to pay the driver.
