The Bronx native also shared a sweet holiday-filtered selfie with Jen to his Instagram story on Christmas, where you can see a hint of a baby bump on the mom-to-be.
Jen is six months long, according to Us. She is already mom to an 11-year-old son, but this will be the couple's first child together. The pair started dating after Ronnie split from Khloe Kardashian's BFF, Malika Haqq, in February.
Luckily, Ronnie will be able to get plenty of advice from his Jersey crew -- Snooki, Paul "Pauly D" Delvecchio and Jenni "JWoww" Farley are all parents now. “They all went through different experiences, which is great,” he told hte outlet.
Snooki dished on the revival during her podcast, It's Happening With Snooki & Joey, earlier this month, revealing that while she couldn't speak to Sammi's specific reasons for not returning, she guessed that her former roommate just "doesn't want to jump back into drama" with her ex.
"Everyone's asking why Sammi's not doing it. You have to ask her that -- I'm not gonna speak for her. But Sammi is just in such a happy place that I feel like she doesn't want to jump back into that drama if it does happen," Snooki said. "And being that there was a lot of Ron and Sam drama when we did film, it was just really hard on both of them. So I just think she doesn't want that anymore."
We have a feeling that, revival and all, Ronnie is looking more to the future than the past now that he's going to be a dad.
