El Moussa and Haack got married in 2009 and welcomed their first child together, Taylor Reese, in 2010. Both their marriage and TV show were doing exceptionally well until he was diagnosed with thyroid and testicular cancer in 2013.
Long hours of filming coupled with the stress of cancer started putting a wedge between them. The problem in their relationship was exacerbated later when they tried to expand their family through IVF, resulting in two failed attempts and a miscarriage.
El Moussa and Haack gave birth to son Brayden James in 2015, but their marriage had already started falling apart.
The pair tried counseling but did not get good results out of the sessions. Ultimately, they filed for divorce in 2017 and their marriage was dissolved in January 2018.
Even after separating, Haack and El Moussa continued their show, Flip or Flop, just like they had before. They also co-parent their two kids.
El Moussa has since moved on with Rae Young. The two got engaged on July 25, 2020, on the day of their first dating anniversary. Their engagement was covered on the October 8, 2020, episode of his show Flipping 101.
