Christina Haack addresses claim she cheated on third husband Josh Hall with boyfriend Christopher Larocca

The ex-girlfriend of Christina Haack’s new man claims the “Flip or Flop” alum is a cheater — but Haack denies any crossover.

Andrea Deanna — who dated Hall’s current boyfriend, Christopher Larocca, for two years — alleged to the Daily Mail on Tuesday, “While we were still dating, [Larocca and Haack] were dating.”

The medical esthetician, 29, further accused Haack, 41, of being unfaithful to her third husband, Josh Hall, whom she is now divorcing.

“She was still married, and they were still living together,” Deanna alleged.

Haack’s rep, who did not immediately return Page Six’s request for comment, told the outlet in response, “This person continues to make false allegations and spread lies. Christina was separated when she met Chris.”

Larocca also “categorically” denied the allegations via a spokesperson, claiming he had “ended his relationship with [Deanna] prior to his relationship with [Haack].” His rep added, “Any statement that they met in June is untrue.”

In January, news broke that Haack had been secretly dating someone new “for months” — although the specific timeline was not disclosed.

The “Flip Off” star was spotted making out with Larocca outside of a Los Angeles restaurant shortly after.

The couple then went Instagram-official in February by sharing photos of themselves on a private jet. Haack captioned the post at the time, “Some plane flights must be hard posted. 🛩️ 🐉.”

A rep for Hall, meanwhile, told the Daily Mail in response to claims his estranged wife cheated on him, “We are not surprised about these rumors at all. What’s surprising is it took this long for a media outlet to contact Josh and ask about it. We’ve been awaiting this question.”

Haack filed for divorce from the real estate entrepreneur, 44, last July after nearly three years of marriage. The reality star — who was previously married to Tarek El Moussa from 2009 to 2018 and Ant Anstead from 2018 to 2021 — stated in the court documents that she and her third husband split on July 8, 2024.

The exes have been involved in a nasty legal battle since then, with the “Christina on the Coast” alum accusing her estranged husband of transferring $35,000 of her money into his account.

She also slammed him as “insecure” due to her success and claimed he had asked her for $65,000 in monthly spousal support. However, he denied those allegations.

The estranged couple do not have a prenuptial agreement, and their divorce case is ongoing.

Meanwhile, Deanna has tried to warn Haack that Larocca may not be who she thinks he is.

“He definitely has a pattern between his ex-wife, his ex-fiancée, me and maybe Haack down the road,” she claimed to the Daily Mail. “I mean, I hope not.”

The social media influencer alleged that when she was dating the Network Connex CEO, he would secretly meet up with his ex-fiancée behind her back.

She added, “Hopefully he learns from his past mistakes, but I don’t think so after the third, fourth time.”
