HGTV star Christina Hall is undergoing major renovations on her personal life — again.

The 41-year-old built a career buying, renovating and re-selling homes for profit on the hit “Flip or Flop” with her first husband, Tarek El Moussa. Now, her third marriage is crumbling and things are getting ugly.

On July 15, she filed for divorce from husband Josh Hall, 43, in Orange County, Calif.

The pair co-starred together on two seasons of “Christina in the Country,” and Josh was also credited on one episode, from 2022, of “Christina on the Coast.”

More recently, they were shooting — alongside El Moussa and his wife, Heather Rae Young, 36, from “Selling Sunset” — a new HGTV series called “The Flip Off.” It was slated to air in 2025.

But, behind the scenes, Christina and Josh hadn’t quite built a happy life together.

“He was really piggybacking off her,” an HGTV insider told The Post. “I’m sure this show ‘The Flip Off’ was probably the last straw for [Christina]. He wasn’t good on camera.”

Christina’s rep, Cassie Zebisch-Schienle, said that her client is “looking forward to moving forward in this chapter of her life.”

The Post has reached out to Hall’s spokesperson and HGTV for comment.

Josh filed for divorce the same day as Christina, citing irreconcilable differences.

“The marriage was strained, but Josh never expected this ending,” a source close to him told The Post.

According to court documents filed in Orange County Superior Court and obtained by The Post, Christina is asking a judge to order Josh to give back $35,000 that she alleges he transferred to his personal bank account the day before she requested a divorce.

Christina feels he was trying to “steal money from her,” a source told The Post.

The source close to Josh disputes that claim.

“He transferred money from a joint bank account solely to pay the bills on one of their rental properties, which he has continued to manage following their separation. It was used in the ordinary course of business. Nothing was ‘stolen.’ Any insinuation that Josh stole or mishandled funds is defamatory,” said the source. “Josh was always very financially responsible with the couple’s money.”

Christina is also asking that Josh pay her attorney fees and seeking to maintain exclusive use of their $12 million Newport Beach, Calif., residence, according to the docs. While the property is in both of their names, she claims that it was purchased by her through the sale of a home in nearby Dana Point.

Josh, according to the source close to Christina, requested spousal support, half of the Newport Beach house and the rights to the HGTV-Discovery Network shows he participated in.

The split has become so contentious that, on July 24, Christina broke her silence on the matter.

“I have worked my ass off to build this life for myself and my children and anyone who would try and take what they do not deserve/what they did NOT work for should be ashamed,” she wrote on Instagram going on to call her ex an “insecure man with a large ego.”

“[Josh] was spending too much money and not contributing financially to the relationship,” the source close to her said.

The person close to Josh claims that isn’t true, saying that “Josh spent 24/7 managing the couple’s businesses” — including their homes.

Christina, a mom-of-three — she shares son Brayden, 8, and daughter Taylor Reese, 13, with El Moussa and 4-year-old Hudson with second husband Ant Anstead – reportedly wanted her kids to see her in a happier relationship.

When she divorced El Moussa in 2018 and Anstead in 2021, she kept things relatively civil because children were involved.

“Co-parenting and communication with Tarek and Ant are in a great place,” Zebisch-Schienle said.

(There was still drama at some points. Her initial separation from El Moussa, in 2016, was proceeded by an incident in which he ran from their home with a gun after an argument. At the time, he said he was going for a hike and took the gun for protection from wild animals, The Post previously reported.)

Things are far less amicable between Christina and Josh — and the pair seemingly didn’t have a prenuptial agreement.

“Christina is being very vocal. The last two divorces she really was like, ‘I’m not going to speak poorly about my ex-husband because he’s the father of my children,’ ” the source close to her said. This time, “she’s fighting back.”

The divorcing duo were first linked in July 2021, when they were spotted holding hands at LAX Airport, just a month after Christina’s divorce from Ant was finalized.

Around the same time, Ant was linked to actress Renée Zellweger, and the two have been together ever since.

“I met Josh when I wasn’t in a state of fear or fight-or-flight . . . I had taken time off social, hired a spiritual coach, and smoked [psychedelic] Bufo toad (which basically reset my brain and kicked out years of anxiety in 15 mins),” she gushed on Instagram in July 2021. “The synchronicities hit us so hard and fast they were impossible to ignore.”

In April 2022, she changed her Instagram name from Christina Haack to Christina Hall, revealing that she had married the Realtor and former cop from Austin, Texas.

They celebrated their union that September with about 40 friends and family at Merriman’s Kapalua on Maui, Hawaii.

“My dream man on the dreamiest island,” Christina wrote on Instagram at the time, with a photo of her and Josh at their Hawaiian wedding.

On Sunday, Josh was photographed moving his belongings – including a vintage Delorean valued at more than $50,000 – out of their shared Newport Beach home.

That same day, he addressed news of the divorce on Instagram, posting a photo of him with his dog.

“I prefer privacy, especially during something as life changing as a divorce I did not ask for. I will not publicly badmouth anyone as people have families, friends and others who respect and love them,” he wrote in the caption.

“We are real humans, this is our life and I am not here to entertain people I don’t know with my private matters,” he continued. “Those details will be handled fairly behind closed doors with our respective counsels in due time. Those who know each of us, know who we are.”

Christina, for her part, seems to be moving forward, indulging with a “much needed” girls’ trip last weekend in Palmetto Bluff, SC.

“The pure peace I felt there was something I haven’t felt in a long time,” she wrote last Sunday on Instagram in a selfie caption.

“She tried to make it work, and there’s a breaking point,” said the source close to Christina, noting that shooting on “The Flip Off” has resumed without Josh. “Things have not been great for a really long time … It’s almost been a weight off her shoulders.”

But, it’s unlikely that this will be the last romantic drama for Christina.

“She goes into these relationships genuinely believing that this is the one,” said the HGTV insider. “She’s in love with love.”
