Jersey Shore

We're told 495 Productions -- the company behind "Jersey Shore" -- hosted a blowout (pun intended) casting call for Season 3 on Monday and Tuesday night at The Crazy Donkey on Long Island with WBLI ... even though a third season still isn't in the bag.

At least one of the guys in attendance was a huge tool ... as in Jordan Alexander from "Tool Academy 3" (the guy with the green star bandana).

The GTL stud hit up a California drugstore and stocked up on magnum amounts of condoms.

The overly-tanned twosome locked lips -- and sunglasses -- while at Tantra Lounge.

It all went down at Tantra nightclub -- one of the few Miami clubs that hasn't already banned the cast -- but we're told the Snooki-Situation lip-lock was just your standard DFM (dance floor makeout). Not to mention, they've sucked face before -- see Season 1.

The 28-year-old inhaled the face of some girl who looked a bit like Jwoww on Monday.

TMZ has learned the reason Snooki kicked her BF to the curb -- and it all has to do with his desire to be on another MTV reality show.

Sources close to the Snookster tell us the "Jersey Shore" star decided to drop her BF Emilio after he auditioned for "The Real World."

We're told Snooki was madly in love with the dude -- but was bothered by rumblings that he was using her for the fame. One source tells us when Emilio tried out for "RW" -- that was the final straw for the Snook.

We reached out to Emilio for comment -- he responded with the following email that will make your English teacher's head explode:

"All i kno is she was upset i tried out fornreal world nd left me a message sayin im single. Next i kno i wake up [Monday] morning and facebook says im single."

If you're interested in a faux Jersey Girl firmly planted in Miami, you're in luck -- Snooki dumped her boyfriend, sources tell TMZ.

We're told the "Jersey Shore" cutie believes her formerly favorite guido was cheating on her.

According to a document obtained by TMZ, The Sitch -- formally known as Mike Sorrentino -- filed for unemployment in New Jersey on October 25, 2009 ... "Jersey Shore" didn't premiere until December 3.

New Jersey then sent a Request for Separation Information form to the restaurant in Florida where Mike was last employed ... to verify that he was really terminated.

As they set to get ready to film again in New Jersey this summer, TMZ has learned the network has requested additional police presence for the cast. According to the Seaside Heights PD, MTV has requested between eight and ten off-duty officers -- the network would pick up the tab.

For those of you who think a grenade is either a weapon or small country in the Caribbean, it's actually an ugly chick who tags along with her hot friend. In Season 1, The Situation typically scored the hot chick, while Pauly D had to fall on the grenade.

We're told only hot chicks get to go back to the house in Miami -- such an honor.

Despite becoming famous, these "guidos" still have their priorities in order.

GTL realness.

TMZ was there as The Situation, Pauly D, Snooki, Jwoww, super buff Ronnie and Sammi showed up to their new digs yesterday and the self-proclaimed "Kim Kardashian of Staten Island" arrived too ... with real luggage -- no trash bags this time.

Ronnie and his situation were there too -- but we gotta know ...
