A timeline of Tarek El Moussa and Christina Haack's romantic and professional relationship, from 'Flip or Flop' to 'The Flip Off'

In the early 2000s, El Moussa and Haack met while working at a real-estate office, as he shared in his 2024 book "Flip Your Life."

They joined forces professionally and personally, and in 2008, the housing market crash hit them hard. According to The OC Register, they had to move to a cheaper home before "Flip or Flop" started.

In 2009, El Moussa and Haack tied the knot on Coronado Island in San Diego.

Shortly after getting married, Haack gave birth to the couple's first child, Taylor.

According to "Flip Your Life," El Moussa had a friend help him film an episode of a reality show that detailed how to flip a home in 2011.

He submitted the episode to a production company, which loved it. The company created a sizzle reel of El Moussa and Haack, and HGTV became interested in making the show come to life.

In 2012, HGTV signed the couple for a weekly program about the process of flipping houses, which would become "Flip or Flop."

The series premiered in April 2013.

As El Moussa shared in "Flip Your Life," a "Flip or Flop" viewer who was a nurse noticed a lump in El Moussa's neck while she was watching the show. She emailed producers about it, leading El Moussa to see a doctor.

He was diagnosed with stage 3 thyroid cancer after exploratory surgery, and he had his thyroid and the surrounding lymph nodes removed. He also underwent radioactive iodine therapy to treat the cancer.

Two months after he was diagnosed with thyroid cancer, El Moussa decided to look into his medical history, and he ended up getting diagnosed with testicular cancer after noticing something abnormal on a test. He had one testicle removed to treat the cancer.

Both cancers are in remission today.

In 2015, Haack and El Moussa welcomed a son, Brayden.

Us Weekly reported that, on May 23, 2016, Orange County police were called to El Moussa and Haack's home in response to a "possibly suicidal male with a gun."

Eyewitnesses reportedly told police they saw El Moussa "run out of his back door, jump over his back fence, and walk northbound into the hiking trails of the Chino Hills State Park."

A witness said Haack was following him and was "crying and shaking." One of Haack's friends was in the home at the time and told police she saw him grab a handgun before he left.

In "Flip Your Life," El Moussa said he left their home "after an especially heated confrontation with Christina" and took a pistol with him in case he saw any wildlife. He also said in the book that he had a concealed carry license for the firearm.

El Moussa also wrote in "Flip Your Life" that Haack called the police, and they took him home in handcuffs after tracking him down via a helicopter, as per their "protocol."

He added that the incident marked the end of his marriage to Haack.

"And that was the very last time we were together as a family: with Christina walking down the driveway, crying, and me sitting there in handcuffs, asking myself, 'What in the world is going on?'" he wrote in his book.

In December 2016, El Moussa and Haack officially announced their separation in a statement to Us Weekly, referencing the firearm incident.

"Like many couples, we have had challenges in our marriage," the statement said. "We had an unfortunate misunderstanding about six months ago and the police were called to our house in an abundance of caution."

"There was no violence and no charges were filed. We chose to get counseling to sort out our relationship. Together, we have decided to separate while we reevaluate the future of our marriage," the statement went on to say.

"During this process, we are committed to our kids and being the best parents we can be," they added. "We will continue to work through this process civilly and cooperatively, and plan to continue our professional life together."

About a month after announcing their separation, El Moussa's lawyer told People that El Moussa had officially filed for divorce and confirmed that he was requesting spousal support from Haack.

In the spring of 2017, amid reports that Haack and El Moussa weren't getting along, Haack spoke to E! News about their relationship.

"The kids are great," she said. "My son is literally like the happiest kid on the planet. He brings so much joy to our lives. Taylor is amazing. She's feisty and funny. She's a very sweet, loving girl."

"Tarek and I are in a very good place right now," she said. "We're doing a really good job. We share the kids 50/50, and our communication is great. Like I said, the kids are happy, so everyone's doing really well."

Haack filed her own petition for divorce in August 2017.

In her filing, she cited "irreconcilable differences," according to People.

During an appearance on "The Doctors," El Moussa said he felt his marriage to Haack failed because of communication issues.

"I feel like if we had better communication, we would have had a better relationship," he told them. "I think as time went on, you get busier and busier. It was like overnight: businesses, TV, all these things happened overnight, then the cancer and the back surgery. It just kind of started pushing us apart from each other."

A representative for the pair confirmed to Page Six that their divorce was finalized on January 22, 2018.

The exes continued to film "Flip or Flop" after the divorce.

Haack and Anstead, a former HGTV star and the owner of Radford Motors, first started dating in October 2017. They tied the knot just over a year later, in December 2018.

They welcomed a son, Hudson, nine months later in September 2019.

Although El Moussa and Haack continued to film "Flip or Flop," Haack also filmed her own HGTV docuseries, "Christina on the Coast," which spotlighted her solo renovation endeavors.

The first season of the series gave HGTV double-digit rating growth, according to a press release from the network.

She went on to film "Christina in the Country" as well.

El Moussa helps new home flippers learn the ropes of the business in "Flipping 101 With Tarek El Moussa."

El Moussa proposed to Heather of "Selling Sunset" fame on their first anniversary.

The couple moved in together after just a week of dating.

On Instagram, Haack shared that she and Anstead were separating after less than two years of marriage.

Their divorce was finalized in June 2021, according to USA Today.

People reported that El Moussa yelled at Haack and compared her to his then-fiancée amid "Flip or Flop" filming.

"Look at me, look at me, look at me. It's called winning," El Moussa said to Haack, according to People. The publication also reported that he called his ex-wife a "washed-up loser" during the incident.

People later reported that a source said El Moussa was "super remorseful" about his comments. But the same source said that Haack and El Moussa weren't friends.

"They're exes who share a history and children and a workplace, but outside of co-parenting, they're not friends," the source told People.

Haack announced she was engaged in a now-deleted Instagram post.

Hall, a real-estate agent based in Austin, and Haack only dated for a few months before he popped the question.

The reality stars said their vows near Santa Barbara, California. Young also officially changed her last name to El Moussa.

They had their first baby together, Tristan, in February 2023.

The duo shared the news in separate Instagram posts, saying a March 2022 episode of "Flip or Flop" would be the series finale.

HGTV confirmed the series was ending in a statement provided to Business Insider, adding that Haack's and El Moussa's individual series would continue.

"Tarek El Moussa and Christina Haack are long-time, fan-favorite stars on HGTV, and it's true that 'Flip or Flop' is coming to an end after an epic 10-season run as a top-rated unscripted series," a representative for HGTV said in a statement to BI. "More than 90 million viewers have watched the popular series since its premiere in 2013."

"We look forward to seeing more of Tarek and Christina's real life, real estate and renovation adventures in upcoming episodes of their solo series 'Flipping 101 with Tarek El Moussa' and 'Christina on the Coast,'" the network added.

Neither Haack nor El Moussa mentioned each other in their posts.

People reported that a source familiar with the situation said, "Tarek and Christina are generally cordial. They're co-parenting, and nothing gets in the way of that."

"The show was just too intimate of a setting at this point, and it was time to close that chapter," the source said.

Representatives for El Moussa and Haack did not respond to a request for comment from BI at the time.

On May 9, 2022, The Daily Mail published pictures of the El Moussas, Haack, and Hall at Brayden's soccer game on May 8.

In some pictures, Heather Rae El Moussa and Haack appear to be arguing, and Hall and Tarek El Moussa look like they are fighting in separate photos. The Daily Mail reported that Brayden's soccer coach had to separate Hall and Tarek El Moussa.

The incident occurred just one day after Heather Rae El Moussa seemed to confirm on the "Selling Sunset" reunion that her husband had called her a "hotter, richer version" of Haack during their on-set fight.

On May 11, 2022, representatives for Haack and Heather Rae El Moussa confirmed they argued in a statement to BI and said they had "resolved" their issue.

"A personal matter was discussed and has since been resolved," the statement said. "We are focused on co-parenting as a team moving forward."

On May 8, Haack shared on Instagram that Brayden had an emergency appendectomy, as well as his Meckel's diverticulum removed.

In an Instagram story she posted on May 9, Haack said the experience was a "wake-up call."

"Stressful 24 hours but a good reminder how important team work / co-parenting is," she said on her story. "We are all under pressure but when it really matters we were all there for Brayden doing our part."

"Sometimes a scary situation can be a good wake up call. In the end all the other stuff is just 'noise,' what matters is the kids," the post went on to say. Haack tagged Heather and Tarek El Moussa, as well as Hall, in the post.

Heather Rae El Moussa posted a similar sentiment on her Instagram story.

"We all pulled together as a family during this stressful time," she said. "The kids will always be the main priority to all of us."

After the show's abrupt ending in March 2022, Haack and El Moussa reunited to film a proper finale for the series later in the year.

The finale aired on December 1, 2022. It showed the exes renovating a 2,200-square-foot duplex home and reminiscing about the series' 11-year run.

In a press release announcing the series, HGTV described "The Flip Off" as "a battle to see who can find, buy, renovate, and flip a house for the biggest financial gain'" in which the El Moussas would compete against Haack and Hall.

The show marks El Moussa and Haack's first on-screen reunion since "Flip or Flop" ended.

Both Hall and Haack filed for divorce in July.

Haack deleted nearly all traces of Hall from her social media following their separation.

The El Moussas spoke to paparazzi about Haack and Hall's separation, saying he wasn't part of "The Flip Off" following the split, E! News reported.

"We support her," Heather Rae El Moussa said.

"Life's tough. Shit happens," Tarek El Moussa said. "We got one shot at life, and we gotta do what's best for us, so whatever she needs, we're here to help."

Haack spoke to Entertainment Tonight about her breakup and "The Flip Off" in an interview that aired on November 15. She told the outlet she "did not enjoy" filming with Hall.

"It was not fun, to be honest," Haack told ET. "I did not enjoy filming with him. So having split up made this, to be honest, so much easier."

She added that filming "would have been hard" because Hall was jealous of Tarek El Moussa.

The El Moussas spoke to ET separately, and Heather Rae El Moussa agreed that filming with Hall wasn't fun.

"I don't want to be mean, but it was kind of nice to see him go," she said.

"The Flip Off" will premiere on January 29, 2025.
