They Gotti find a new home!

Victoria Gotti’s palatial Long Island estate — which she and her sons once flaunted in the reality show “Growing Up Gotti” — is now under foreclosure.

Despite a vast fortune amassed by her late father, Gambino boss John “Dapper Don” Gotti, the flashy Mafia princess has skipped two years of loan payments and will lose her home in tony Old Westbury, according to court records.

The 46-year-old former reality-TV star owes $650,000 to lender JPMorgan Chase — a debt secured by a mortgage on the nearly $4.2 million mansion that she won in her divorce with ex-husband Carmine Agnello.

“I was awarded full ownership of marital property . . . and all I inherited was a house with millions of dollars’ worth of debt,” Gotti told The Post yesterday.

“This should finally put to rest all the government lies and rumors that I have $200 million buried in my back yard.”

The couple split in 2003, while Agnello was serving a prison stint for racketeering, and the grandiose, 6-acre home was deeded over to Gotti in 2005.

But Gotti claims Agnello had secretly taken out an $850,000 loan in 1997 without her knowledge and has left her holding the bag.

Not so, according to lawyers for the bank, who convinced judges with the Brooklyn Appellate Division that Gotti is crying wolf.

Last week, the appeals court gave the bank a green light to start foreclosure proceedings and reversed a Nassau County judge’s ruling that would have allowed Gotti more time to fight the case.

“Good riddance,” said one neighbor on Birch Hill Court, who asked not be identified.

This isn’t the first time Gotti has faced losing her house.

Upon taking ownership of the house in 2005, Gotti immediately defaulted, and JPMorgan scheduled to auction off the estate that summer — even as she and her three hair-gel-loving sons preened for the cameras for “Growing Up Gotti,” which ran from 2004 to 2005 and was canceled after 41 episodes because of poor ratings.

Gotti persuaded the bank to give her an extension on the mortgage with the condition that she would pay $200,000 by February 2006, at a rate of $25,000 each month.

Court records show Gotti forked over an unspecified portion of the cash — and then stopped paying.

In the latest ruling, the appeals court granted JPMorgan’s request for summary judgment and ordered Nassau County Supreme Court Justice Roy Mahon to appoint a referee to determine how much money is owed and whether the property can be sold in one lot.

The estate, which Gotti once tried to sell at $4.8 million, is currently listed with Century 21 at $3.2 million, a source said.

Since its reality-TV days, the estate’s grounds have turned into an eyesore.

Unlike the landscaped lawns that surround neighboring homes, Gotti’s unkempt property is covered with weeds and moldering leaves. Trash is spilling out of overturned garbage cans and loose wires hang from the security intercom.

Parked in the estate’s driveway yesterday was a Cadillac Escalade with a sticker that read, “Free John Gotti Jr.” The SUV was next to a Mercedes and a BMW.

Her brother, John “Junior” Gotti, won three mistrials in federal court in Manhattan after his lawyers argued that he had left the Mafia prior to the five-year statute of limitations for racketeering.

He is behind bars awaiting his fourth trial on a slew of charges, including murder.

“I never took a penny from anyone in my life — not from my parents, not from anyone. I am far too proud,” Victoria said, adding that her ex-husband doesn’t even help her when it comes to their three kids, Carmine, John and Frank.

“I am still in court fighting for what was awarded to me,” Gotti said about money awarded to her in the divorce case.

“Yet the government still insists the divorce was . . . a sham. They insist Agnello and I are only trying to save assets.”

Meanwhile, Agnello is living in Ohio with his new bride — the raven-haired daughter of Mourad “Moose” Topalian, a former leader of an Armenian terror organization.

The feds are still seeking to claim $11 million in penalties stemming from Agnello’s 2001 conviction and are in the process of selling off commercial and residential properties in The Bronx and Queens.

“Carmine lives a rich and luxurious life,” Gotti fumed. “I have to give Agnello a big cheer. He outsmarted . . . the entire government.”

Contacted at her home in Howard Beach, Queens, Gotti’s mother, also named Victoria, said of her daughter: “She’s very upset. This is a hard situation.”

Agnello is “a creep. He’s a deadbeat. She didn’t know anything about it,” the mother said. “He’s not paying child support. He gave her a real screwing.”

Lawyers for Agnello declined to comment.

Records show the Dapper Don’s daughter was hit with a $36,096 state tax lien on one of her properties December, and she also owes more than $45,000 to St. Francis Hospital from a 2004 judgment.

While the mortgage on the manse went unpaid, she was buying and selling other properties for hundreds of thousands of dollars, including a Pennsylvania home that once belonged to her brother.

In October 2008, Victoria was listed as the new owner of her mother’s Howard Beach home and also bought a Queens warehouse that had been owned by her and Agnello.

That building was one of several properties she had refused to pay property taxes on and then quietly bought back after they went into foreclosure.
