It’s not just their kids that keep Tarek El Moussa and Christina Haack together since the successful home-flippers ( Flip or Flop) went their separate ways and got remarried. The two are back for more real estate ventures on The Flip Off, a throwdown competition that airs Wednesdays on HGTV.

During The Flip Off premiere, Christina Haack announced her divorce from Josh Hall amid their intense house flipping competition and revealed her ex's jealous side was a factor in their messy breakup.
