Jersey Shore

Nothing's official yet -- but according to sources close to the reality star, the deadline for negotiations is Monday ... so we should have a definite answer by then.

The foul-mouthed female is Deena Nicole Cortese -- the same chick who sucked down a beer bong with Snooki in Seaside Heights this weekend.

Turns out Deena recorded a video blog on her MySpace page back in 2008 -- in which she rants about the way she's been treated by some dudes ... swears revenge ... and then says to the camera, "We're gonna play you out, n**ga."

Sources close to production confirm Deena will be appearing in a number of episodes during the third season of "Jersey" ... but she isn't considered a "permanent" cast member.

Question is ...

Sources connected to the show tell TMZ Angelina will not be returning to "Jersey" ... but The Situation, Snooks, Pauly D, Jwoww -- even Ronnie, Sammi and Vinny ... will all be back.

A source involved in the negotiations tells us a deal was struck late last night -- and Snooki is thrilled to death with the terms.

As far as the money goes, the source wouldn't tell us an exact amount, but noted, "Definitely great compensation."

According to the manager, Mike "The Situation" Sorrentino "believes he and MTV have reach [sic] a great new arrangement." No mention of dollar amounts, but interestingly, the manager says the deal was sealed (though he never says it's been signed) with MTV, and not JS producers 495 Productions.

TMZ broke the story ... MTV offered The Sitch anywhere between $27,500 to $45,000 per episode over a period of time -- he was making $10k for season 2, so not bad.

But move over Moses -- Sitch's manager says, "Mike decided in order to get season 3 done he was going to have to lead the pack and wants to encourage the rest of his cast to follow his lead."

SallyAnn Salsano, executive producer of the show, tells TMZ they are ready to shoot. Salsano says they are "committed to the show" and "ready to go."

As we first reported, the cast has refused to shoot scenes for season three until a new deal is in place.

Snooks accidentally posted her BBM to her Twitter account -- which has over 310,000 followers -- and we're told her phone exploded nearly instantly with the torrential wave of messages she received from fans.

According to sources close to the reality star, Snooks had to ditch her phone and get a new one -- making her completely unreachable for hours.

TMZ broke the story ... members of the cast went on strike yesterday, refusing to shoot over the weekend for Season 3.

Sources connected with 495 Productions tell TMZ the cast is ultimately hurting the show. As one source put it, "The show is not about famous rich people with managers coming to the Shore."

495 would like to keep a few of the cast members -- notably The Situation, Snooki and Pauly D -- but they think the strike by the cast is the last straw.

We're told the cast feels like they've been tricked, because they felt their contract -- which gives each of them $10,000 an episode -- was only supposed to cover Season 2 in Miami. They feel they're being screwed now that producers want them to go to the Shore and shoot another installment under the existing deal.

As we first reported, The Situation is being tempted with a sweet new contract and we're told it's pissed off some of the other cast as well as the crew.

Here's the rub ... Sources say MTV thinks they have "magic in a bottle" with this group and wants to keep the cast intact.

The cast was supposed to begin shooting "at home" scenes today for season three, but we're told Jwoww, Ronnie, Sammi, Pauly D and Vinny -- who are spread out between New York and Rhode Island -- told the crews they weren't shooting without new contracts.

The Situation and Snooki are supposed to shoot tomorrow, and we're told Snooki plans to do the same. No word yet on The Situation, but as we first reported ... he's having contract issues of his own.

Sources close to the show tell TMZ the cast feels they can make more money doing appearances for two months, rather than filming the show.
