The drama is only just getting started for Flip or Flop stars Tarek and Christina El Moussa!

Shortly after In Touch revealed that the pair may be calling off their divorce due to contractual obligations to HGTV, an insider has exclusively told In Touch more details about the drama that lead to their explosive fight, during which the father-of-two stormed out of the house with his guns.

The drama began when they hired Christina’s now-boyfriend Gary Anderson — an “older, wealthy divorcée” who was hired as a contractor when they decided to redo their pool back in 2015.

“Christina grew close to Gary,” the insider tells In Touch exclusively. “Tarek was suspicious that she was getting involved with someone but had no concrete evidence.”

That changed in May. “Tarek saw Christina’s phone and [believed] there was some inappropriate texting going on between Christina and Gary,” the insider notes, adding that that incident led to Tarek blowing up and storming out of their home with his guns.

In a statement to In Touch, the estranged couple says, “Neither of us was involved in a romantic relationship with any third party prior to our separation, or believes the other was.”

Christina has since confirmed she’s dating Gary — who has his own skeletons in his closet, as In Touch previously revealed he lied about his hefty income in order to pay less spousal support when his own marriage fell apart.

Unfortunately, Christina and Gary’s relationship may soon be put on hold — and not because of the endless drama. A network insider with HGTV tells In Touch the network has threatened to take the couple to court for breach of contract because they are “more profitable” as a marriage pair.

“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.’”
