Mark Sanchez’s baby mama Erin Campaneris was holed up at her parents’ house in Arizona this week after taking a swipe at the embattled former Jets quarterback following his stunning arrest, The Post can reveal.

Campaneris, who also goes by Bobby T, was spotted Tuesday walking with her 8-year-old son outside her family’s modest 1,300-square-foot condo owned by her mom and dad, Bert Campaneris — a legendary retired shortstop for the Oakland Athletics.

The 46-year-old UK-born supermodel and ex-gal pal of Sanchez was sporting a red gingham pattern column maxi dress and mesh Mary Jane shoes.

A few days before the public stroll, Campaneris threw shade on the NFL quarterback-turned-commentator last week after he was charged with a felony for allegedly beating a 69-year-old truck driver to within an inch of his life in Indianapolis.

“Sadly, none of this is surprising to me,” she wrote on an Instagram Story Sunday.

Campaneris’ mother Evelyn told The Post her daughter isn’t permanently living in the house, which is worth about $500,000 — suggesting the model and her son are crashing there until the heat dies down.

Evelyn declined to comment on the Sanchez drama, claiming a lawyer had told her to keep quiet.

“My foremost priority has always been, and remains, our eight year old son, Daniel. I chose to remain silent publicly to protect Daniel,” Campaneris wrote in Sunday’s social media post.

“I have always been concerned for [Daniel’s] safety and for what he is exposed to,” she added.

Sanchez hasn’t been Campaneris’ only high-profile fling: She got together with London-based actor Will Poulter — of “The Bear” fame — in 2022 before the pair split earlier this year, according to The Sun.

“[Campaneris’] main priority will always be her son and she lives in America, which is fine when Will is working there but can be hard work,” an insider told The Sun.

As for her NFL baby daddy, the couple began dating in 2017.

Sanchez married actress Perry Mattfeld in May 2023, and she revealed in February that she was expecting twins with Sanchez.

The couple first met in 2017 while she was in Chicago filming “Shameless” and he was playing for the Bears, and were introduced by Sanchez’s teammate Scotty McKnight, but the pair also had a lot more in common.

“We both went to USC, both actually born at the same hospital, both Hispanic, a lot of weird things,” Mattfield told Glamour in an interview last month.

Sanchez was processed by the Marion County Sheriff’s Office on Sunday, eight days after he was stabbed in the chest following an altercation with 69-year-old grease truck driver Perry Tole in Indianapolis.

Tole was parked in a hotel loading dock in an alley when the Fox Sports analyst allegedly confronted him about a parking spot, according to court documents.

Sanchez is now facing a level 5 felony battery resulting in serious bodily injury charge along with three misdemeanor charges, battery resulting in injury, public intoxication, and unlawful entry of a motor vehicle.

He is next due in court on Nov. 5 after an initial hearing in the case set for Oct. 7 was waived.

Tole has also filed a lawsuit against Sanchez seeking civil damages.

The 69-year-old claimed he “suffered severe permanent disfigurement” in the attack and was badly injured in his head, jaw and neck, according to the suit.
