For years, Christina and Tarek El Moussa invited fans behind closed doors on Flip or Flop — saving even the most physically broken of homes. But there’s always been one home they can’t fix — and that’s their own.

Shortly after it was revealed that the couple is divorcing, In Touch has learned that their marriage was always a “façade,” with an insider adding, “There were secrets, lies, allegations of cheating, spying on each other, and screaming matches. It was the ultimate house of horrors.”

And now, a network source with HGTV exclusively tells In Touch that their personal problems are quickly impacting their professional life, as the network believes the show is at stake now that they’ve called it quits and the skeletons are coming out of their closet.

“This is getting really ugly,” the network source tells In Touch, exclusively. “HGTV is livid with Tarek and Christina. Flip or Flop just won’t be the same if they’re not together, so execs desperately want them to reunite to save the show. If they can’t do that, the network wants to make it seem like they’re getting along, at least until their contract is over. They were given an ultimatum: Either finish out your contracts or we’ll take you to court [for breach of contract]. The network basically said, ‘You guys need to work together, be seen together as a family, walk down the street together.’”

And so far, they seem to be cooperating — for the cameras at least. And it would appear that’s nothing new for the controversial couple.

“They would literally fight in that house and then sit down at their computers and post everything nice for the world to see,” their neighbor explains to In Touch. “They were living a double life. They weren’t only working on a reality show — they were putting on a show.”
