In the last-ever episode ofFlip or Flop, Tarek El Moussa and Christina Haack don’t exactly see eye to eye.
After taking a full tour around the property, El Moussa says, “I hate dealing with flips that have pools because they can cost a fortune.” Haack, on the other hand, tries to focus on the positive: “Look on the bright side, we also get to do a fun design.”
Haack then lists some extravagant ideas she has for the design: “We could do that really cool glass tile or, because it’s Spanish, maybe a cool clay tile. What about a waterslide?” As she goes through her list, El Moussa is far from excited as he says “no” and starts walking away. “Fill it up with water,” he says, before exiting the frame.
Though the conversation is mostly playful, and not out of the ordinary for the exes, it does underscoresome of the on-set tensionsthat haveseemingly led to the show’s end, which was announced abruptly just last week.

A source with knowledge of the situation told PEOPLE, “Tarek and Christina are generally cordial. They’re co-parenting and nothing gets in the way of that,” adding, “Theshow was just too intimate of a settingat this point and it was time to close that chapter.”
A few days after the news broke, an insider told PEOPLE of the show’s end, “The writing has been on the wall for a while. It was not sudden.”
Last summer, ablow-up on setalso came to light, revealing tensions between the pair.
During the confrontation, Tarek reportedly screamed at Haack, comparing her to his now-wife,Selling Sunsetstar Heather Rae El Moussa, and calling his ex a “washed-up loser,” according toTMZ, who first reported on the incident.
A source later told PEOPLETarek was “super remorseful"that he “lashed out,” but noted, “They’re exes who share a history and children and a workplace, but outside of coparenting, they’re not friends.”

Haack told PEOPLE exclusivelylast week, “I will be forever grateful to have had a series for a decade. It’s a huge accomplishment and everyone who worked on the show should be very proud.”
“The series made it through ups and downs and trust me it wasn’t always easy,” she added. Haack and El Moussa went through a public divorce in the middle of the series' run and have been navigating co-parenting and new relationships on screen since. Tarek married Heather Rae last October and Haack is engaged to realtor Joshua Hall after marrying and divorcingCelebrity IOU: Joyridehost Ant Anstead.
Haack is focused on the future, she said. “I’m looking forward to my next chapter and working in positive, fun and creative environments. I’m ready to let go of the stress and enjoy life and all it has to offer.”
