MTV

Sources tell TMZ the "Jersey Shore" money machine scored a $400,000 signing bonus to be the spokesman for a vodka company called Devotion.

But this ain't no ordinary booze -- Devotion contains a clear protein called Casein ... which can support an increase in lean body mass and a decrease in body fat if the user is also on some sort of weight training program.

We're told The Sitch's brother, Marc Sorrentino, brokered the deal through the company they run together, MPS Entertainment.

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."

As The Sitch got off his plane from Miami -- where he was just shooting Season 2 of "Jersey Shore" -- dude told us his next step is to "jump into film."

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.

Taylor tells TMZ she was driving through Fort Worth on I-35 North Tuesday afternoon when the car in front of her rear-ended another car ... and she didn't have enough time to stop before she came crashing in too.

According to Taylor, the Hummer received around $14,000 in damages ... and she had to spend six hours in a nearby hospital for the concussion she suffered ... as well as a sprained neck and bruised shins.

According to our sources, MTV just picked up Pauly D in Rhode Island and then grabbed The Situation in New York City before heading south. We're also told Snooki and Jwoww are in another ride -- and are also en route.

We're also told MTV is keeping the stars on total lockdown -- our source says the network has banned the use of cell phones during the trip.

Puck from "The Real World: San Francisco" is hospitalized in San Diego following a terrifying car wreck that left the reality star and his 8-year-old son seriously injured ... this according to sources close to the family.

We're told Puck was driving down Route 79 on Friday to go on a father-son fishing trip, when he swerved to avoid a deer and lost control of his car.

The car rolled down an embankment and landed upside down in a creek. Sources tell us Puck -- real name David Rainey -- was trapped, but he managed to free his son, who flagged down some help.

The two were transported to nearby hospitals where doctors discovered Puck had broken bones in both feet, his right hand, his neck ... and fractured his sternum and clavicle.

We're told his son had bruised several internal organs in the wreck -- he also suffered major damage to his liver.

Two random high school students hit up Mr. Dogg outside the Eldridge lounge on the Lower East Side and one of them had an iPod version of a resume. Snoop listened to the kid's original tracks and was so impressed, he ordered his manager to get the boy's contact info.

Sources say MTV camera crews will start paying visits to the homes of Snooki, The Situation, DJ Pauly D, Ronnie, Vinny, Jwoww, and Sammie this coming weekend to tape them as they attempt to cram their giant egos into carry-on luggage.

We're told the cast is supposed to fly out to Season 2's mystery location some time next week.

No word yet on whether Angelina made the cut ... if anyone actually cares.

Season two of the popular MTV reality will film in Florida, according to the Miami Herald. The production company behind the show has been scouting locations in Miami since last month, as TMZ first reported.

A source close to the show tells TMZ they will begin filming before the month is out.

Debra Danielson -- mother of 18-year-old Farrah Abraham -- copped a plea. If she stays clean and complies with probation, the case will be dropped.
