Ouch.

Lenny Hochstein’s latest Instagram may cut his estranged wife like a knife — a pizza knife.

The plastic surgeon, 57, shared a few snaps of him hosting family night on Wednesday at the Star Island mansion he used to share with Lisa Hochstein.

Taking pictures of him making pizza pies with their two kids, Logan, 8, and daughter Elle, 3, was apparently Hochstein’s new fiancée, Katharina Mazepa, whom he thanked for being a “master chef.” Dad and his kids were all wearing aprons, and big smiles.

Meanwhile, mom vacated the sprawling, historic home at the end of August, as per the exes’ prenup. The “Real Housewives of Miami” star is still fighting to invalidate the contract signed back before their 2009 wedding in Miami-Dade County court.

It’s unclear where the 41-year-old reality star is now residing, though things have become serious with her businessman boyfriend Jody Glidden; the fellow Canadians began dating in the spring. So perhaps the snaps of her estranged husband cooking in her old kitchen with Mazepa and the kids doesn’t sting.

But it’s doubtful. The divorce, initially filed by Hochstein back in May 2022 after being seen around town with the Austrian model, is still quite contentious.

Page Six reports that the day Lisa Hochstein had to move out was “awkward” and “chaotic.” An insider told the outlet that the so-called Boob God showed up on the property while all his estranged wife’s stuff was being removed.

“He made the move really uncomfortable. She was trying to do her best to get everything done,” the source said. “He kept interfering. He should have been at work.”

Lenny Hochstein admitted to being there, but accused the Bravo star of taking more than agreed upon.

“About three days before the move she told me she was going to take much more than I would agree. And in that case there was a disagreement and we would go to court or mediation,” he told UsWeekly in a statement. “Lisa completely ignored that and not only did she take much more than I had agreed to, she essentially cleared out my house.”

Regardless, anyone who has been a fan of “RHOM” remembers many scenes shot at that Miami Beach property over the years, even before the Hochsteins had kids.

Commenters were mixed under the doctor’s post.

“Life is short and one has the right to seek happiness. Lenny looks happy. The kids look happy. At the end of the day, that’s all that really matters. Stop the hate.”

Another sided with mom: “She had no choice. This has to hurt real bad.”

“I’m glad you’re happy,” wrote another. “But I can’t help to feel bad for Lisa. This must be so painful for her.”

A case management hearing was set for Thursday and another on Sept. 18, as per court records.
