The reality star did a photo shoot with his soon-to-be-ex wife Kate and their eight children in the city.
But while Kate schlepped the kids back to their home in Pennsylvania, Jon hit the town for dinner at posh Upper East Side Italian restaurant, Accademia di Vino.
A spy at the restaurant told OK!: “Jon arrived at around 8pm and they joined four other people.
“She didn’t talk so much — she was kind of quiet — but he was very nice. They stayed for around an hour.”
But the big question: was it a date?
“Possibly,” says our source. “It’s not like they were making out at the table or anything. On the other hand, they definitely arrived together and left together.”
Another eye witness tells us that the pair then headed off into the night together on foot.
The girl in question is Kate Major, a reporter for a low-rent tabloid, who has told the New York Daily News that she and Jon are “just friends.”
But right now Jon’s social life has our heads spinning. We wonder how the kids must feel about it…
