HGTV star Tarek El Moussa and Heather Rae Young have welcomed their first child together.
The couple announced the arrival of their son in a joint Instagram post on Thursday, sharing a picture of the newborn cradled in their hands while wrapped in a blanket.
"Our baby boy is here 🤍 1.31.23," El Moussa wrote in the caption. "Mama & baby are happy, healthy, tired but doing well. Our hearts are so happy ❤️."
Friends and followers flocked to the comment section to congratulate the couple, including Young's fellow Netflix "Selling Sunset" co-stars Jason Oppenheim and Chrishell Stause, and TV presenter Ant Anstead, who was previously married to El Moussa's ex-wife Christina Hall.
"Yay!!! So excited for you two (three!!!!). 😍😍😍," Oppenheim wrote.
Stause commented, "Omg sending SO much love your way!!! 🥰🥰🥰🥰."
"HUGE congratulations you guys! ❤️," Anstead wrote.
Even the official HGTV account got in on the celebration, writing in the comments, "Welcome to the HGTV family little one!"
El Moussa, 41, and Young, 35, who tied the knot in October 2021, received the news about their pregnancy while undergoing in vitro fertilization treatments last year.
"It was a huge shock," Young told People Magazine in July. "We just weren't expecting this. We had just gone through IVF. We had embryos on ice. We had a plan."
"I think when you least expect it and there's no stress in your life, the world just brought us what was meant to be. I'm so excited that it happened like this," she added.

In January, Young opened up about being a stepmom to El Moussa's kids and how supportive the children have been throughout her pregnancy.
"Not everyone can understand the close relationship I have with the kids & that's fine, all that matters is how we feel," she wrote in an Instagram post. "The kids made me want to have kids, I love my role as their bonus mom❤️."
"For anyone who's asked me about how the kids have been throughout my pregnancy: my honest answer is that they've been amazing. Bray checks on me constantly and is so sweet about my belly and Tay couldn't be more excited to have another baby brother," Young added. "She is so caring beyond her years. And told daddy 'if I'm at school and Heather goes into labor call the school right away so I can talk to her & tell her good luck & I love her.'"
