Tarek El Moussa’s so perturbed about word of his on-set eruption on his “Flip or Flop” costar getting out, he’s gone to Herculean lengths to make sure it doesn’t happen on his own show … by eliminating any potential rats.

Production sources Tarek’s team went to the production company after we posted our story about him flipping out on his ex-wife, Christina Haack, and demanded that any crew member who was working on “Flip or Flop” that day be removed from the staff of his spin-off series, ‘Flipping 101.’

We’re told Tarek was pissed because he believes someone on that crew leaked the story about him going off on Christina, and the production company — which produces the show and “Christina on the Coast” — shifted some workers around to accommodate his demand.

However, a source close to Tarek tells us the crew change request was more about wanting a group that is excited for him and his fiancee, Heather Rae Young … and one the couple can trust to not leak any upcoming wedding spoilers.

As we told you … Tarek was accused of yelling at Christina on set last month after she signaled it was time to begin filming, and allegedly it wasn’t the first time he’d done this.

A source close to Tarek claimed his anger toward his ex-wife stemmed from her recent admission she smoked toad venom … and he was concerned about what else she was doing around their kids.

Regardless, he doesn’t have to worry about run-ins with Christina on his spin-off — which is gearing up for its second season … and if he gets his way he won’t have to worry about any ‘Flipping 101’ leaks either.
