Their baby boy! Tarek El Moussa and Heather Rae El Moussa (née Young) have documented their sweetest moments with son Tristan following his January 2023 arrival.

Before welcoming their first child together, the couple frequently opened up about their plans to expand their family. The real estate investor, for his part, shares Taylor and son Brayden with ex-wife Christina Hall (née Haack).

“Tarek treated me like a wife from the beginning and he was so supportive of me being a stepmom to the kids right away, but there’s something extra special about officially being the El Moussa family,” Heather wrote via Instagram shortly after exchanging vows with Tarek in October 2021. “These kids are truly our everything, so we decided to say our vows first to the kids and second to each other. This is just a tiny portion of what I said to the kids, but I truly meant every word: When your daddy and I decided to be fully committed, I was 100 percent committing myself to you too. I am beyond honored to be your bonus mommy. Thank you for allowing me to love your daddy with all my heart. I love you both more than you will ever know.”

In July 2022, Heather and Tarek announced her first pregnancy. Ahead of their little one’s arrival, the pair gushed over how excited they were to meet their baby.

“Oh, my God, the kids are so excited! I mean, Brayden has been tracking the growth of the baby every single week with Heather. He talks to the baby and he rubs her belly. Taylor too. Both of the kids are so excited,” the HGTV personality exclusively told Us Weekly in December 2022.

At the time, the former Playboy model hinted that fans would be able to see certain milestones from her pregnancy. “We filmed [the baby shower] for Selling Sunset. It was an all-girls shower,” Heather teased to Us. “[Tarek] did come and crash it at the end, though, which was exciting. There might have been a little fight, not between me. I was hanging out with my mom and my sister, but I did see a little spat happening at the next table. You’ll find out.”

Heather gave birth to Tristan in January 2023. Weeks later, the duo offered a glimpse at their first days at home with their baby boy. “Having my own [child] and carrying him and then going through the labor … it’s just such a beautiful thing that the female body can do,” she exclusively shared with Us in February 2023. “All the firsts … it’s a little nerve-wracking.”
