Tarek and Christina El Moussa have put on a good front since their separation of approximately six months became public late last year.
Sources say they are far less cordial in private, however.
The Flip or Flop twosome resumed filming this week amidst a divorce that few fans of the hit HGTV show could’ve ever seen coming.
But are they really as amicable as they’ve repeatedly said over the past few weeks, or flipping out on each other behind the scenes?
A recent report from Radar would tell you the latter.
“Tensions are ridiculous on the set with Tarek and Christina,” an production insider said. “Tarek yells at her in front of production."
"He is constantly putting her down,” the source adds.
“He says he blames her for leaking information about their split and he thinks that she sabotaged their marriage,” the insider claims.
It’s still unclear how that information went public.
Last spring, Tarek stormed out of the house with a gun after a blowout fight with Christina. No charges were filed over the "misunderstanding."
TMZ broke the story, however, and thanks to a statement they put out afterward, we learned Tarek and Christina El Moussa separated.
The insider says Christina may have leaked the story, knowing it would hurt his chances of getting his own series after Flip or Flop.
At least that’s what her estranged husband thinks.
According to this source, Tarek El Moussa "even seems to think that now she is trying to sabotage his chances of getting a spin-off.”
Whether that’s even remotely true is debatable, but we do know Christina had started a relationship with a new man, contractor Gary Anderson.
We also know that this report isn’t unique.
While both reality stars are still saying the right things in public – Tarek slammed fake news and gossip this week – questions linger.
A new report from In Touch Weekly suggests that Tarek and Christina now have separate publicists, following years of sharing representation.
As co-hosts of the aforementioned HGTV series, that’s somewhat significant, given how committed they are to their show and family.
The magazine claims that the signs of problems don’t end there, as Tarek would insult Christina with "vulgar language" in deleted scenes.
Tarek, the source claims, even threatened her, "[saying] he would perform a heinous violent act against Christina on more than one occasion."
He allegedly made Christina run into the car and "cry" in between takes due to his inappropriate behavior and incessant anger issues.
That last rumor is consistent with the infamous fight last year, when Christina El Moussa was reported to be "shaking" as Tarek stormed out.
After the scandal broke, Tarek and Christina acknowledged it and said:
"[We] will continue to work through this process civilly and cooperatively, and plan to continue our professional life together."
"We are committed to our kids and being the best parents we can be."
The parents to Taylor, 6, and Brayden, 1, were reportedly forced by the network to put their differences aside and honor their contracts.
That means finishing the season they’re already committed to, but beyond that, it looks like this may be all she wrote for Flip or Flop.
For the record, Tarek denies all of this, and even felt the need to issue a comment about it, which he has typically refrained from doing.
He didn’t address the specific, scathing allegations made in recent days, but his statement speaks for itself when he calls it all "lies."
He even takes a shot at "fake news," as other famous people have.
"I will keep my focus on what matters most, which is co-parenting our children and working hard on our business," he says.
And he’ll do so despite "the lies, innuendo, salacious gossip and ‘fake news’ that is thrown at me from irresponsible media outlets via anonymous sources."
Whatever you believe, that’s a quality denial right there.
Not overly defensive, but not mincing words either.
