Jersey Shore

Sources close to the deal tell us Jwoww -- real name Jenni Farley -- just signed a one-night deal to appear on Spike TV's "TNA iMPACT!" on Thursday.

We're told Jwoww doesn't have a match scheduled ... but she'll "probably be mixing it up" with a couple of "Jersey Shore"-alike wrestlers named Robbie E. and Cookie.

But Jwoww ain't doin' the wrestling thing for free -- we're told she's pulling in a cool $15 grand for the night ... and the two sides are working out a deal to get her to come back to the show.

The Sitch's manager (pictured above) tells us the car was only a rental -- and it was the manager's rental, not The Situation's. The manager tells us he was backing up the car and didn't notice the truck behind him had its lift down -- so when he hit the lift and tried to pull forward, it ripped the bumper almost clean off.

Sources tell us the "Jersey Shore" star has partnered with Australian Gold to launch a lotion called "Jwoww's Black Bronzer" -- complete with a bottle she helped design herself.

We're told Jwoww will make $2.50 off of every bottle sold ... and she's been guaranteed a minimum of 25,000 bottles sold -- for a cool $62,500. The product is set to hit stores by the end of the month.

It all went down in Hollywood ... right after Sitch left Playhouse nightclub with a few members of his crew. The "Jersey Shore" star rolled into a waiting SUV and took off ... but moments later, the car was stopped on the side of the road ... next to an LAPD squad car with flashing lights.

It's unclear why the police got involved -- but both The Situation and his friends got out of their SUV and had a friendly exchange with the officers ... who never got out of their squad car.

One of The Situation's non-grenades -- Samantha the moaner from last week's "Jersey Shore" -- came to L.A. to see her man on "Dancing With the Stars" and to deliver a message to the haters.

Samantha told us girls who claim Sitch is "small" are big fat liars, because he is... well, big and fat.

Question is ...

Buxom "Jersey Shore" beauty Jwoww has become quite the heavyweight.

While getting in some GTL time in Jersey this weekend, J's trainer used her as part of his upper body workout.

Kerry -- who you may remember as the girl who had that crazy bug bite incident -- tells us she was partying after her victory when she had a run-in with Angelina over VIP access at the club. The two girls ended up leaving at the same time, when they exchanged words and a series of trashy insults ... before they were eventually separated.

Angelina had no problem telling us she started the whole thing -- it stems from an old beef involving Kerry and her ex-boyfriend, the Seaside Heights cop. She told us, "I started the fight. She’s a loser and honestly she’s gonna get it. I’ll f**k her up.”

Neither was born in the United States.

Vinny's 2011 Mercedes-Benz was towed early Thursday morning in New York City ... so our tow sources say.

Vinny parked his ride in a no-no zone on Wednesday night outside of his buddy's place -- and awoke to discover he was Mercedes-less.

According to sources at The Palazzo, residents are required to sign a no-noise agreement before they move in -- and if they get even one complaint after that ... it's eviction time, no excuses.

Strict noise policy aside, the joint is pretty sweet -- we're told they have a Saturday brunch by the pool and also boast a fully functioning spa.

But in all seriousness ... The Palazzo is a giant, swanky apartment community the size of a small city that happens to be located right near the CBS lot where "Dancing with the Stars" shoots. We're told he had his eyes on a unit that ran more than $5k per month ... but no sweat off his brow -- "DWTS" picks up the tab.
