Jersey Shore

Ronnie Ortiz-Magro left a mess behind after his baby mama allegedly dragged him with a car ... and TMZ has some bloody shots of the vehicle.

In the photos, blood streaks can be seen on the outside of the ride we're told Jen Harley was driving when she and the 'Jersey Shore' star got into a fight Sunday coming home from a Vegas BBQ. You'll recall ... Jen allegedly hit Ronnie in the face, then dragged him when he tried to get out.

As you can see ... the vehicle also suffered a flat tire, which we're told was the result of Jen driving over the median when she took off ... with their 2-month-old daughter, Ariana, in the car.

There's also a shot of the interior console covered with blood ... possibly from Ronnie's injuries after being struck in the face.

Harley was arrested for domestic battery and booked at the Clark County Detention Center. She was also the suspect in a battery investigation for allegedly spitting on and hitting Ronnie 3 weeks ago during another argument.

Ronnie Ortiz-Magro's friends are warning the 'Jersey Shore' star to cut ties with his baby mama, out of fears her latest domestic violence arrest is a bad omen of what's to come if he stays with her.

Sources close to Ronnie tell us he's been trying hard to have a good relationship with Jen Harley because he's worried she'll take full custody of their daughter. We're told that's the only reason he was at a BBQ with her Sunday, hours before she allegedly dragged him outside their car.

Ronnie's friends are telling him it's time to quit playing family man and look out for his safety and his daughter's, and they say that means staying away from Jen. We're told friends are also advising him to handle the custody situation in court, because there's no upside to reconciling with Jen at this point.

TMZ broke the story, Harley allegedly attacked Ronnie in their car on the way home from a Vegas BBQ. We're told their 2-month-old daughter, Ariana, was in the car at the time ... and there's growing concern she could be caught in the middle of any future fights.

Harley was also named the suspect in a battery investigation after she allegedly spit on and hit Ronnie 3 weeks ago during an argument over their daughter and dead dog.

Ronnie Ortiz-Magro from 'Jersey Shore' was allegedly dragged by a car driven by his baby mama, Jen Harley ... and she's been arrested for domestic battery.

Jen was busted late Sunday in Vegas after she and Ronnie got into a fight while driving home from a BBQ. Sources close to the exes tell us Jen hit Ronnie in the face during the argument, and he demanded she pull over and let him out of the car.

We're told Ronnie got caught in his seatbelt, but Jen took off anyway ... dragging Ronnie. Worst of all ... we're told their 2-month-old daughter, Ariana, was in the car at the time.

Harley was booked for domestic violence at Clark County Detention Center

We're told Ronnie's face was bloodied and bruised and, as you'd expect, he's got a nasty road rash. Also, none of this was for cameras ... "Jersey Shore" was not shooting Sunday.

Ronnie from 'Jersey Shore' came THIS close to an all-out brawl on the second day of filming season 2 in Vegas.

The incident went down Wednesday at a pool party at the Flamingo ... where Ronnie had to be restrained from going after some loudmouth. You can see from the start of this video Ronnie was charging at the guy, but both were restrained by the massive security team present. It's unclear what triggered the confrontation.

You can also see several cameras are rolling ... so the guess here is MTV cameras captured it for the show. Check it out ... the man Ronnie's beefing with keeps shouting something about Gucci and hustling.

'Jersey Shore' outcast Angelina Pivarnick's made her return and, even though it got a little nasty with the crew, she says they went out on good terms ... until JWoww started running her mouth again.

Angelina tells TMZ ... despite a heated confrontation with JWoww and Snooki on Thursday night's episode of "Jersey Shore Family Vacation," she was actually in a decent place with everyone once her reunion with the cast was done filming.

Then ... she heard JWoww was trashing her about a fan's Change.org petition, which Angelina claims is both immature and incorrect. She tells us this is what led to her "Jersey Whore" diss toward JWoww last week.

There's a soft side to this feud, though -- Ang concedes JWoww's a good person and respects her for being a good mom ... but believes they need to work out their differences in a more grown-up way.

Ronnie from "Jersey Shore" allegedly got into a physical confrontation with his baby mama ... and it was caught on video.

Ronnie's baby mama, Jen Harley, took to Instagram Live on Monday and posted this video showing Ronnie in a heated argument with Jen in the upstairs part of someone's house. A second woman is seen downstairs trying to get Ron to chill out before all hell breaks loose.

The video shows Ron and Jen, who is holding the phone, getting into a scuffle ... with Ron telling her to get off of him. The video cuts out for a few seconds as a struggle ensues. The fight stems from a series of Instagram story posts by Ron over the weekend ... blasting Jen of being a "natural born HOE." Our friends at TooFab meticulously broke it all down.

Pauly D is calling for MERCY for Tristan Thompson ... saying Khloe Kardashian should give the dude a second chance after getting caught cheating on her during her pregnancy.

"OHHHHH," Pauly told us while outside 1 OAK in Hollywood ... "He got caught up there!"

He certainly did ... footage of Tristan motorboating, kissing and messin' around with other women (not named Khloe) surfaced this week as Khloe is getting ready to give birth to their kid.

Still, Pauly says he hopes Tristan gets another shot to be the faithful baby daddy Khloe wants.

JWoww says Sammi Sweetheart's sex doll stand-in offered some good times for the 'Jersey Shore' cast ... but it sounds like she misses the real McCoy.

We spoke to Jenni 'JWoww' Farley Thursday ahead of the premiere of their reunion season on MTV, and she tells us Sammi REALLY should have joined her fellow guidos and guidettes for their comeback ... rather than be recast with plastic.

We broke the story ... 'Jersey Shore' producers replaced Sammi with a sex doll version of herself, which J says was done all in good fun ... maybe too much fun, actually. Sounds like that doll's been through some things. We'll let her explain.

Either way, JWoww says Sammi missed a huge opportunity to cash in on her "Jersey Shore" fame, even if she's in a "different place" now ... post Ronnie Ortiz-Magro, whom she dated during the OG run.

J seems to think folks should finish what they started, and that goes for Sammi, too -- who, btw, was apparently made aware of the sex doll gimmick. Maybe she'll reconsider for Season 2 ... which JWoww says is greenlit.

Sammi "Sweetheart" Giancola won't be on the "Jersey Shore" reunion, at least not in the flesh, but the crew won't be a woman down since she's being replaced by a sex doll.

Doug Weldon is the owner of hotsexydolls.com and tells TMZ that someone from production approached him in early January about making a replica of Sammi for the reunion since she wouldn't be returning.

Sammi, who dated Ronnie Ortiz-Magro during the original six-season run of the show, said she opted out because she's in a different place in her life than she was during the first run of the show.

Enter Doug, who says he was told the doll would be a huge part of the show, but making a carbon copy of Sammi's face was a no-go since it would've taken 6 weeks, and there wasn't enough time before filming started.

Production bought a standard 5' 5'' doll from the website that Doug reduced to C cups. He also provided them with two female heads and made them look like Sammi ... using the right shade of makeup along with 4 wigs, so production could match her hairstyle. Total cost ... $1,840.

Doug says he shipped the goods to Miami in a box that the crew can be seen opening in the trailer. We're told it makes its official debut in the first episode.

Snooki's reaction is priceless ...

Don't let this egg-stravagent photo of Jenny McCarthy and the cast of "Jersey Shore" scramble you up ... look on the sunny side of this image and you may just find a few Easter egg surprises.

Mike "The Situation" Sorrentino got burned for not paying taxes, but now it might be tax season that buys him more time as a free man.

Mike's facing up to 5 years in prison for tax evasion charges after pleading guilty in January. Sentencing's set for April 25, but his lawyer, Henry Klingeman, is asking the judge to push that back because Mike's accountant is buried in tax returns through the middle of the month. 'Tis the season.

As part of Mike's plea deal, he had to resubmit his 2010 to 2012 returns, and his accountant has to review 1,500 pages of financial info to finish them up.

Mike "The Situation" Sorrentino's in a dancing mood checking out luxury whips ... probably because he doesn't have to stress about dropping cash on one of them.

The Sitch was with his 'Jersey Shore' pals Ronnie, Vinny and Pauly D Monday in Miami filming for their reunion show, and visited an exotic car dealership to take a couple badass rides for a spin.

Ronnie took the wheel of a Lambo, with Mike riding shotgun -- while Pauly D and Vin hopped in a Bentley.

The sad situation is ... Sitch ain't getting any closer than a test drive. As we reported, he recently pled guilty to tax evasion, and owes a big check to the IRS. He's also looking at up to 5 years in prison and a hefty fine.

Mike "The Situation" Sorrentino went booze-less during the "Jersey Shore" cast's first official night out.

Paps got Mike out Tuesday night with the rest of his GTL crew at a South Beach club, and he was clutching a Red Bull can the entire time.

Meanwhile, Pauly D and co. definitely partied it up and had bottle service at their table -- but the Sitch went dry throughout the night.

In case you're wondering, Mike's no-booze policy doesn't appear to be tied to his tax evasion case -- in which he just pled guilty last week, and is set to be sentenced later this spring.

On the contrary, Mike's said he's been "100 percent" sober since 2015 after battling a Rx drug addiction.

The cast of "Jersey Shore" has finally reunited in Miami ... and the drinks are already flowin'.

We got pics of Ronnie, Pauly D, Snooki, JWoww and Deena toasting to what's sure to be a fun next few days. Missing are Vinny, Mike "The Situation" Sorrentino -- who was in court in New Jersey Friday -- and Sammi Sweetheart who took a pass on the reunion to avoid a run-in with ex Ronnie.

More good news for Mike "The Situation" Sorrentino -- prosecutors in his tax evasion case are pushing for the judge to give him a lighter sentence.

As we reported ... Mike entered a guilty plea as expected Friday, and the judge okay'd him to travel to Florida to shoot a "Jersey Shore" reunion.

Still, the Sitch's looking at up to 5 years in prison. According to new docs, prosecutors believe he played a minor role in the tax evasion, and point out he's accepted responsibility for his actions. They're making a case for leniency when the judge issues his sentence in April.

On the money front, the docs say Mike has to fork out $123,913 in restitution to the IRS. The judge could also tack on a hefty fine at sentencing.

Mike "The Situation" Sorrentino is coming clean with Uncle Sam -- he's agreed to plead guilty in his tax evasion case in New Jersey.

The Department of Justice and the U.S. Attorney's Office in New Jersey filed docs, obtained by TMZ, informing the judge about the "Jersey Shore" star's plea. It's unclear which charges Mike pled guilty to, and if he struck a deal ... though all signs point to a plea deal.

Mike's brother, Marc, also faced criminal charges and also agreed to plead guilty.

We broke the story ... Mike allegedly failed to pay his full tax bill on $8.9 million in earnings made between 2010 and 2012. Prosecutors had said he intentionally filed fraudulent returns to make it look like he was all good with the IRS.
