Tarek el moussa blows up at ex-wife christina haack on flip or flop set: 'it's called winning'

Tarek El Moussa flipped out at Christina Haack on the set of _Flip or Flop_ last Wednesday, PEOPLE can confirm. El Moussa, 39, reportedly lashed out at his ex-wife and co-host, _TMZ_ first

reported. After he didn't like the way she signaled to him that she and the crew were ready to film the next segment, El Moussa went on a verbal tirade against Haack, 38 — with whom he

shares daughter Taylor, 10, and son Brayden, 5 — comparing her to his fiancée, _Selling Sunset_ star Heather Rae Young, and saying that he enjoys watching her fail, the outlet notes.

"Look at me, look at me, look at me. It's called winning," El Moussa reportedly yelled at Haack, exclaiming that he "made" her and referred to her as a

"washed-up loser." The pair were married from 2009 to 2018, and both found fame with the launch of their series _Flip or Flop_ on HGTV in 2013. They also both now have solo series

on the network, Haack's _Christina on the Coast _and El Moussa's _Flipping 101. _ Haack and El Moussa have filmed nine seasons of _Flip or Flop_ together and are currently working

on Season 10. The show follows the divorced duo as they navigate life as co-parents and real estate experts flipping run-down homes in California for a profit. A rep for Haack did not

immediately respond to a request for comment. HGTV had no comment. El Moussa also allegedly told his ex-wife that Young, whom he proposed to in July 2020, is more attractive and richer than

she is, and that, "The world knows you're crazy." Haack recently made news after it was revealed she's in a relationship with Austin-based realtor Joshua Hall, whom she

began dating after her divorce from her second husband, Ant Anstead. She and Anstead were married for less than two years, and share a son, Hudson London, 22 months. Earlier this month,

Haack admitted to smoking psychedelic toad venom as part of a spiritual journey before she met Hall, which she said, "reset my brain and kicked out years of anxiety in 15 mins." A

source told _TMZ_ that this admission is part of the reason why El Moussa had pent-up anger towards Haack, as he's concerned about the safety of their children. RELATED VIDEO: CHRISTINA
