The "Selling Sunset" and "Flip or Flop" stars first confirmed their relationship in August 2019 after rumors they were together started swirling a month earlier. Two years later, the couple celebrated their love and got married in October 2021. 

Earlier in 2022, Young opened up about her fertility struggles and the moment she found out she might have a difficult time getting pregnant when the time came. She remembered feeling devastated to learn about her low egg count, especially since she was still in her 20s and thought she still had time to think about children.

In an interview with E! News, she revealed that while she had frozen her eggs in 2019, she had decided she wasn’t going to use them, but things changed when she fell deeper in love with El Moussa and saw what an amazing father he was. She also fell in love with his children and being a stepmom.

"Seeing Tarek with his kids really made me want a baby with him — because he is just such an incredible a father to them," she told the outlet. "And, you know, I love watching them grow up in front of my eyes… I started thinking, ‘Gosh, if I have this much love for them, how can I not have my own baby?'"

In a separate post, Young expressed how excited she was to be having a baby of her own and gushed over her step kids. 

"The most fun part of it all is how sweet and supportive Tay and Bray have been. They try to guess the gender and are having so much fun coming up with names," Young wrote on Instagram. "And it’s so cute, Bray comes up to me every day we have the kids and says, ‘Hhow big is your baby today?’ And he’ll put his ear to my belly and say, ‘I can hear the baby.’"
