• Tarek and Heather Rae El Moussa said they both didn't want to have kids when they first started dating
  • She said she changed her mind about having children after seeing her husband's love for his two kids
  • Heather is thankful to have Tarek's support in their IVF journey

Tarek and Heather Rae El Moussa are opening up about their plans to expand their family and their IVF journey.

The "Flip or Flop" host and the "Selling Sunset" star tied the knot about three months ago, with Heather undergoing in vitro fertilization in hopes of having a baby.

The couple told Entertainment Tonight in a new interview that both of them initially agreed that they didn't want any children.

"Originally when we first met, it was like I said, 'No I don't want any kids.' He said, no more kids for him. So we were on the exact same page," Heather told ET. "Well, fast forward two-and-a-half years… you know."

"Someone changed the page," Tarek added.

The real estate agent later changed her mind after witnessing Tarek's love for his two children, Taylor, 11, and Brayden, 6, whom he shares with ex-wife Christina Haack.

"To be honest, it was my love for Taylor and Brayden and honestly seeing Tarek as a daddy. Like, he loves those kids, he's so obsessed with them and when we don't have them, he's like, 'I miss them. I miss them,'" she explained. "And I do too. We love having them around, we miss them, and just seeing him be such an incredible dad I think that really started changing my mind."

The couple was also influenced by Heather's mom, who is already looking forward to her grandchild.

Tarek, meanwhile, ultimately changed his mind about having another child after seeing his wife be "such a rock star [step]-mom" to Taylor and Brayden.

Heather has been open about her IVF journey on social media. She has been visiting the doctor and has frozen six eggs, recently wrapping her second round of egg freezing.

According to the realtor, they discussed freezing embryos as she had a low egg count and Tarek previously had testicular cancer.

"It's definitely been rough," Heather said of the process. "These last two-and-a-half weeks, poking myself every single day with needles, three times a day, the hormones, the emotions... At first we found out I only had two eggs. Which going through this whole process and only finding out I had two eggs, I was sad. I did cry a little bit and, you know, going into the extraction -- we went to the extraction on Tuesday. I came out and I had seven eggs, so that was really exciting for us because we thought we only were gonna get two."

At present, they continue to track how many eggs and embryos Heather has. They then do genetic testing to make sure that everything's good, and in less than two weeks, they will find out "how many babies we have on ice."

Tarek said they hope to add another member to their family "within a year," but Heather hopes it can be as soon as "next month."

"I think now that it's in my mind, because I was a 'no' and then it was like, 'OK, let's think about it. Let's maybe do this,' and then now that I'm like, 'OK, I'm ready and I'm ready to be an official Mommy and be pregnant,' mentally I'm there," Heather explained. "I'm ready! Sooner than waiting another year or two."

Throughout their journey, what Heather has been most thankful for is having the support of Tarek, especially as she goes through "a lot of emotions." She described him as the "best husband."

Tarek and Heather married in a lavish ceremony in Santa Barabara on Oct. 23, 2021, more than a year after getting engaged.
