Christina Haack Proves She's 'The Boss' On 'Flip Or Flop' Set After Tarek El Moussa Fight

Christina Haack showed the world that she is "the boss" on the "Flip or Flop" set after her dispute with ex Tarek El Moussa.

Haack seemed to be throwing some shade at her ex-husband after news of their heated disagreement on set made the headlines. She took to her Instagram Story and shared a clip showing how smoothly the filming process was going for her without El Moussa, People reported.

Haack shared a series of videos while on the set of "Flip or Flop," which is currently filming its 10th season. In the first video, she wrote, "Nice day on the Flip or Flop set" as the camera panned to show the crew members walking around and El Moussa was noticeably not present.

In another video, she appeared to be filming with a contractor. "Alright, well it's looking great, so since Tarek's not here I say we carry the tile all the way behind the vanity," she told him.

"All right, you're the boss," a crew member said.

Hack nodded and said, "I'm the boss," as she walked away.

In the other video, Haack repeated that El Moussa was not present to make any decisions on the Costa Mesa, California home that they were renovating. She stressed that they have to do it her way and a crew member responded to her, "You're the boss."

An anonymous source confirmed with the outlet that El Moussa lashed out at Haack while filming their hit HGTV show. He reportedly went on a verbal tirade because he didn't like the way she signaled him that she and the crew were ready to shoot the next segment. He compared his ex-wife to his fiancée, "Selling Sunset" star Heather Rae Young, and told her that he enjoys watching her fail and even declared, "The world knows you're crazy."

"Look at me, look at me, look at me. It's called winning," El Moussa, 39, said.

He also allegedly told her that he "made" her and referred to her as a "washed-up loser."

Haack also seemed to have thrown some shade at El Moussa on Instagram on the same day they had a fight when she shared a snap of her with her new boyfriend, Joshua Hall. She posted a selfie of them together in a car and described him as her "ride or die."

"Ride or Die. Some people are lucky enough to get forever the first time but no one should be shamed for things not working out and no one knows what goes on behind closed doors," she wrote. "Remember that before making judgements and assumptions… and this woman / mama is still lucky enough to have this man choose me."
