Nicole 'Snooki' Polizzi Explains That 'Ruin My Marriage' Moment From 'Jersey Shore' Trailer (Exclusive)

The reality star also opens up to ET about feeling 'mom guilt' while filming.

Nicole "Snooki" Polizzi reunited with her former co-stars for Jersey Shore Family Vacation, but it was her real family back home that she couldn't stop thinking about. 

The reboot released an explosive new trailer on Thursday showing the cast getting back to some old shenanigans -- which had Snooki worried about the fate of her marriage. 

ET's Katie Krause spoke with the reality star and mom of two on Thursday as she promoted the show at Hyde Sunset in Los Angeles, and revealed what was behind that shocking comment that something might "ruin" her marriage to Jionni LaValle. 

"I cant really talk about it, because I want everyone to watch, but it's just me being drunk and dramatic and I just worry so much about Jionni, like, getting mad about things that he would never get mad about," Snooki explained. "So when I'm drunk, I'm like, 'Oh my god, you said I looked pretty! You cant say that!' Like, it's all in my head and I'm crazy, so you'll see it play out. I'm an a**hole."

"Listen, old things do come up, because we're together and that's going to happen," Vinny Guadagnino told ET of his former relationship with Snooki. "But at the same time, I'm pretty sure her marriage is all right." 

The trailer also teased an argument between Snooki and her BFF, Jenni "JWoww" Farley, but according to Snooki, it's nothing out of the ordinary. "Me and Jenni are sisters. We always fight like that, so you're going to see us fight like that a lot," she said. "She's, like, so annoying, but I love her. She's my big sister." 

"Listen, I thought I was wild before I had kids. Me and Jenni partied the hardest we've ever partied in my entire life," Snooki continued. "Like, I would wake up like, 'Oh, I'm hungover, but hey, let's go get mimosas.'"

"Honestly, for me, I'm a full-time mom, 24/7 at home with the kids, waking up at seven, dropping them off at school, doing laundry, cleaning the house, like, that's my life," she expressed. "So the fact that we had a vacation to where I could just do whatever I wanted, I was like, 'I'm gonna drink.'"

That's not to say Snooki didn't second-guess her decisions. The MTV star told ET that while fans will "see the kids a little bit," and she got to visit her family once during filming, she actually experienced a lot of "mom guilt." 

"The second day there, we were at a bar and I heard one of the Trolls songs come on. It's my daughter [Giovanna's] favorite song, [my son] Lorenzo's favorite song and I started crying. I go, 'Oh my god, I miss my kids!'" she recalled. "Then my husband will call me like, 'Oh, you know Giovanna has the flu,' [I'm] getting mom guilt like, 'Oh cool, because I'm gonna go to a bar and have fun and my daughter is sick at home and she needs me.'"

"So we kind of struggled with that, but at the same time, like, just have fun with it. This is a show that we never knew was gonna come back, so the mom guilt was serious," Snooki said. 

As for the recently announced season two, Snooki said she hopes the show makes a few changes. "I'm hoping that we're not away from our families like that again, because I cannot leave my kids like that again," she explained. "So I'm down for it as long as it's a different kind of format."
