Tarek El Moussa broke his silence on the reported feud between him and his ex-wife Christina Haack on the set of "Flip or Flop."

El Moussa spoke with E!’s Daily Pop and addressed the rumored fight between him and Haack on the set of their reality show. He expressed his regrets over what happened in the interview.

"Christina and I, we worked together, wow, for over 10 years now and we’ve been working together as exes for five years now," the 40-year-old realtor 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. … The whole thing just sucked for everyone involved."

He added that he "certainly" would take the moment back if he had the chance. He also vowed that it would never happen again.

"I mean, honestly, since we got into that little disagreement a few months back, I’ve just decided that moving forward, never again," he said.

During their feud, he allegedly compared Haack to his fiancée, Heather Rae Young, and yelled at his ex, "It's called winning. The world knows you're crazy!"

The "Christina on the Coast" star reacted by sharing a photo of her boyfriend, Joshua Hall, on Instagram. She called him her "Ride or Die."

During the interview, El Moussa said he was hoping that they could move forward from the incident for the sake of their two children, Taylor, 10, and Brayden, 6. Haack also shares 2-year-old son Hudson with ex-husband Ant Anstead.

"I never want to go through that ever again, I never want her to go through that again," he continued. "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."

Meanwhile, El Moussa allegedly demanded to remove the crew present during his "Flip or Flop" fight with Haack from his spinoff "Flipping 101." An unnamed source told TMZ he was upset that the feud leaked to the press.

However, a source close to El Moussa said he only wanted to work with a group that is excited for him and Young. Also, they prefer a crew they can trust not to leak their wedding plans.
