The BFFs and former "Jersey Shore" stars moved out of the Seaside Heights home four years ago (after six seasons) but the girls took a trip back and they bought their new life co-stars with them -- their children.
They even took their little ones to the infamous "smoosh room," something that didn't exactly sit too well with Jenni's husband Roger, who shared a photo of the kids in the room known for it's, well, between-the-sheets activities.
"For reasons unknown my wife and Nicole took our kids to the Jersey Shore house today and let them pose for a photo op in the 'Smoosh Room' or as I like to call it the DNA Daycare," he joked about the photo. "This room glows like plutonium under a black light yet they let our kids in there @jlavalle5."
The photo shows Jenni and Roger's kids — daughter Meilani, 23 months, and son Greyson, 1 month — and Snooki and Jionni LaValle's kids — Lorenzo, 3, and daughter Giovanna, 19 months — all sitting on a bed. But thankfully they all all too young to understand what those walls have seen.
"I'm in a full Haz Mat suit now waiting in the driveway to power wash my kids off and scrub them down with bleach when they get home. Child protective services will be waiting for you as well @jwoww," Roger joked, before adding, "Our daughters face says it all."
He later shared an insanely adorable video of his daughter and Snooki's daughter playing with the legendary duck phone.
Jenni shared the same video, taken by her nanny, along with the caption that said, "These two up to no good!!"
Snooki, though, couldn't leave her former residence without visiting the her old quacking friend, either.
JWoww, meanwhile, visited an old mirror.
"Shore house lol #wereback @snookinic," she said.
Feels like we're GTL'ing all over again.
