A source explained the couple are attached at the hip, which means Zack will surely make his reality TV debut. "They're pretty much living together because he stays at her house all the time. They really do not spend any time apart from each other and Jenni is excited for her fans to get to know him."
The new lovebirds were already planning a future together. "He makes her feel so beautiful and so special. They are very much in love and have been discussing their plans for a long life together, including the possibility of kids," the insider added.
As fans know, Jenni, 34, filed for divorce from husband of three years, Roger Mathews, in September, 2018.
Leading up to their split, the parents of son Grayson, 3, and daughter Meilani, 5, were constantly at war with each other.
In December, Jenni filed for a restraining order after an alleged domestic violence incident at the home they used to share in Tom's River, New Jersey.
In April — during the live podcast of "It's Happening with Snooki & Joey," starring cast mate Nicole "Snooki" Polizzi and her pal Joey Camasta — Jenni revealed that she was dating Zack, who she said was only "24!"
"24 is 24. We're filming 'Jersey Shore' right now and we nicknamed him 24," Jenni said when asked about the numerical nickname.
When questioned about her relationship with Roger, Jenni added, "I wish it was over but it's not, so I decided to move on and I moved on with a 24-year old!"
Since then, however, Jenni and Zack, who was a longtime family friend prior to their relationship, have gone very public with their romance — making their red carpet debut at the CMT Awards in June.
Aside from Roger signing off on Jenni's relationship with Zack, it seems that he their kids also approve of their mom's new man!
"I've spent a lot of time with the kids," Zack told Entertainment Tonight in a recent interview. "I've known Meilani for a few years. She's known me for a couple years, she is great with me. I love the kids. They're great."
