Miami- Kristopher Hinson, multimillionaire co-founder of the reality porn website bangbus.com, and ex-wife Cherie Hinson, a Miami Beach real estate agent, are back in court. She claims he filed a fraudulent financial affidavit in their 2005 divorce, and she says she’s entitled to more money — upwards of $10 million.

Kris, 34, and Cherie, 29, were married for two years, no kids. The divorce was uncontested.

She now says he provided low-ball figures on his financials. Kris listed the value of their five-bedroom waterfront residence at 4750 North Bay Road at $5.55 million. That’s what they paid in May ’04. She says she did not know he had obtained a ”secret” appraisal that came in at $9.1 million. She learned of it through a ”quirk of fate” — when “Kris failed to pay for the appraisal and the appraiser, Gary R. Twist, sought payment from [Cherie] at her real estate office.”

She also says Kris may have undervalued his net worth. In a March ’05 financial affidavit, he listed it as $13.6 million. But in a November ’04 affidavit, he put it at $27.2 million, her attorney, Gerald Kornreich, says in court papers. (Kris’ business interests include baitbus.com.)

And, Cherie says, he failed to list $250,000 worth of Miami Heat tickets.

She says Kris persuaded her to waive her right to delve into his finances, saying ”she should save money on attorney’s fees and she could always trust him.” She didn’t know he had a pregnant paramour who ”had his baby approximately two months after the . . . divorce,” she says.

Kris’ attorney, Barry Wayne, says Cherie’s allegations are a ”sham.” She agreed to the marital settlement, and it made her a “multimillionaire.”

Cherie ”had every opportunity and ability to form her own opinion of the fair market value” of the North Bay Road home, Wayne adds. (Cherie, a Fortune International Realty associate, specializes in ”high-end luxury properties in the Miami Beach area,” according to cheriehinson.com.)

Both Kris and Cherie were ”aware of each other’s assets,” Wayne says in court docs. It was she who ”requested her attorneys cease further inquiry” into his finances, even though her lawyers advised her she could “be entitled to a greater amount of money or benefits.”

As for Kris’ girlfriend, she is ”irrelevant” to the case, Wayne says.

Wayne, who did not represent Kris in the ’05 divorce, also argues that Cherie accepted ”millions of dollars in cash and property” plus monthly ”lump sum payments” and thus ”ratified” the settlement agreement.

Cherie, who resides on San Marino Island, recently had a baby — a boy. Kris also has a boy.

Miami-Dade Circuit Judge Bernard Shapiro has the case.
