'Jersey Shore Family Vacation' Spoilers: Ronnie Ortiz-Magro and Jen Harley Fights Revealed

The relationship drama between reality star Ronnie Ortiz-Magro and his estranged girlfriend Jen Harley is slated to take center stage in Jersey Shore Family Vacation Season 2, out Thursday.

On Wednesday, MTV released a teaser trailer ahead of the show's anticipated return. The clip depicts the Jersey gang—Ortiz-Magro, Nicole "Snooki" Polizzi, Paul "DJ Pauly D" DelVecchio, Vinny Guadagnino, Mike "The Situation" Sorrentino, Jenni "JWoww" Farley and Deena Nicole Cortese—fist-pumping and partying their way through cities like Las Vegas and their stomping grounds in Seaside Heights. Things begin to go downhill, however, with the arrival of Harley.

Harley first appeared on Jersey Shore Family Vacation Season 1, where she entered the group's Miami home after Ortiz-Magro attempted to hook up with another woman. This time around, Ortiz-Magro—a man who once famously said "never fall in love at the Jersey shore"—appeared to be distraught over drama brewing between him and Harley regarding the custody battle of the pair's daughter, Ariana Sky Magro.

"There's no one that does relationship drama better than Ron," Guadagnino said in the trailer. This comment is followed by a suggestion from DelVecchio, saying: "You get joint custody, and then she can't say: 'I'm taking the baby.'"

Tension rises between the tumultuous pair. In the next shot, the former couple can be seen engaging in a heated exchange. The argument takes a turn for the worse, however, as Harley appears to get physical with Ortiz-Magro. From there, emergency respondents seem to hit the scene.

"You're driving me crazy," Ortiz-Magro told Harley. She, in turn, suggested Ortiz-Mago was "a f***ing psychopath" before seemingly laying her hands on him.

This wouldn't be the first time Harley has behaved violently toward Ortiz-Magro. In June, Harley was arrested on domestic charges for allegedly attacking the Jersey Shore star. At the time, the pair apparently got into an argument upon leaving a barbeque in Las Vegas. Ortiz-Magro reportedly asked for Harley to pull over to let him out of the vehicle. In doing so, she apparently drove off despite Ortiz-Magro being caught between the vehicle's seatbelt.

Angelina Pivarnick, formerly known as the "Staten Island Dump" and "Dirty Hamster," is to Jersey Shore Family Vacation as well. She spoke with Newsweek about what fans can expect to see during Season 2.

"It's a lot of drama. It's a lot of fun. It's a very crazy season. Better than last season," Pivarnick, 32, told Newsweek. "A lot of stuff goes on and I'm really happy to be back. I'm really fortunate. MTV's amazing. The show is just going to be so much better than last [season]. You just have to tune in! It's going to be a lot of crying, happiness, family, just fun partying [and] babies."

Jersey Shore Family Vacation airs Thursdays at 8 p.m. ET on MTV.
