Tarek El Moussa is coming clean about a blowout fight he had with his ex-wife, Christina Haack, on the set of "Flip or Flop" over the summer.
Back in July, reports said Tarek lost it on the set of the HGTV show and ripped Christina, claiming he "made" her and dubbed her a "washed-up loser." The fight was so bad that the duo had to film their scenes separately.

While speaking to E!'s Daily Pop, Tarek regretting his role in the verbal blowout.
"Christina and I, we worked together, wow, for over 10 years now and we've been working together as exes for five years now," he said. "As you can imagine, it can be stressful working with an ex and we did have an incident where some choice words were said on both sides and I'm sure we both wish the whole thing never happened."
He added, "I mean, I certainly do, but I mean, honestly, since we got into that little disagreement a few months back, I've just decided that moving forward, never again."

TMZ said behind-the-scenes spats between the former couple have happened before. During the fight over the summer, the webloid said at the time, Tarek was incredibly angry with his ex after she admitted to smoking toad venom before meeting her new boyfriend Joshua Hall. Tarek believed Christina's decision was reckless, considering they have two children, Taylor, 10, and son Brayden, 5.
"I never want to go through that ever again, I never want her to go through that again," Tarek said of the fight. "I know one day our kids are going to be older and I want them to know that we still care about each other and we still support each other, and it's really important to me. The whole thing just sucked for everyone involved."
Christina and Tarek split in 2016 and finalized their divorce in 2018. She later married Ant Anstead, with whom she has a third child. She and Ant divorced in June 2021. Tarek is engaged to "Selling Sunset" star Heather Rae Young.
