Tarek El Moussa thinks Christina Haack will get married for a fourth time

Asked how many more times he thinks Christina will tie the knot, he told UsWeekly: "At least [one more time]!"

Tarek is now married to 'Selling Sunset' star Heather Rae and has two-year-old Tristan with her but also has Taylor, 14, and nine-year-old Braden with Christina.

Meanwhile, Christina has five-year-old son Hudson with Ant and she stars alongside her first husband and his wife on 'The Flip Off', but the three of them have been going on double dates with her new partner Christopher LaRocca.

Tarek said: "The double dates are actually fun. The new guy she's dating, I really like him. He's really nice.

"Honestly, he just seems like a good guy. She's going through a really tough situation and, based on my conversations with her, he's supportive, he's guiding, he's experienced and he is giving her good advice.

"So far, everything's looking good.

"So far, so good. We're all hopeful."

Tarek admitted that even in their professional life, things are going well as they continue to host their HGTV show together.

He said: "The show gave me and Christina an opportunity to apologize for things we did to each other. It gave Christina and Heather an opportunity to bond even closer. I mean, we're going to dinners now. So, honestly, it's just about working together, spending time together and creating some really fun TV together."

Meanwhile, Tarek is also gearing up to host the third season of his own show 'Flipping 101' and teased that there are some "wild" things coming up this time.

He said: "The season's a lot of fun because you have inexperienced people putting their entire life savings on the line, trying to flip houses, not knowing what they're doing.

"When we actually filmed the show, the market was more unstable than it is today. So, it's kind of a wild season. ... There was a lot of high-risk flips we did."
