In November, El Moussa spoke with Fox News Digital about how his second marriage would be different from his first.

"I'm in a different place in my life," he said. "I'm older. I have money. I'm not shut down in my mind. I'm wiser. I have more experience. It's completely different."

A cancer survivor, the reality TV star said being diagnosed in 2013 made him "question [my] life, what I know, who I am, where [I'm] going, who I want to be. It's definitely a life-changing, very scary thing. After beating cancer and thriving, you get something called appreciation, and you become grateful for the life you have."

El Moussa said his divorce from Haack forced him to grow as a person.
