Tarek tells PEOPLE exclusively how he found out his ex-wife and her second ex husband were “besties” 4 years after their contentious divorce

Tarek and Heather Rae El Moussa met in 2019. Now, they're starring in two HGTV series together, including "The Flip Off" with Christina Haack.

"Josh and I always had struggles filming together, and I was worried about that going into it," Christina Haack told Yahoo Entertainment of her ex-husband.

Tarek El Moussa and Christina Haack have made their mark on the home renovation game. The formerly married couple, once synonymous with HGTV’s Flip or Flop, turned real estate drama into must-watch television across 10 seasons.

Christina Haack, who is starring alongside her ex-husband Tarek El Moussa and his wife Heather Rae El Moussa in “The Flip Off,” explained why she believes that her estranged husband Josh Hall's exit from the series was for the best.

On the premiere of HGTV's The Flip Off, fans were introduced to Christina Haack's new partners that replace her now-estranged husband, Josh Hall.

Christina Haack wore her heart on her sleeve in the series premiere of The Flip Off. In the Wednesday, January 29, episode, the star opened up to her first ex-husband and costar, Tarek El Moussa, about the pain she privately endured after they ended their marriage.
