Tarek El Moussa/instagram Pregnant Heather Rae El Moussa Is "Having the Most Fun" Dressing Her Baby Bump in Different Styles Heather is already stepmom to husband Tarek El Moussa's two children: daughter Taylor, 11, and son Brayden, 7, whom he shares with ex-wife Christina Hall. The couple had been open about their efforts to conceive, with Heather documenting her fertility journey on Instagram. She said she chose to share the "very personal journey" publicly to "create awareness." In July, the couple revealed exclusively to PEOPLE that they are expecting their first child together early next year. They were in the middle of in vitro fertilization (IVF) treatments when they found out they were expecting. "It was a huge shock," Heather told PEOPLE at the time. "We just weren't expecting this. We had just gone through IVF. We had embryos on ice. We had a plan." RELATED VIDEO: Tarek and Heather Rae El Moussa Are Having a Baby: "We Weren't Expecting This!" The day they found out, Tarek, 41, was sitting in a Zoom meeting and recalled having a strange feeling, explaining, "I was like, she needs to take a pregnancy test right away." After two inconclusive tests, the third showed a positive result, prompting Heather to take two more for good measure. Tarek has also praised his wife for how she has handled the pregnancy, while juggling work and family responsibilities. "In awe of how amazing Heather has been doing throughout her pregnancy," he wrote in an August Instagram post. "Still coming to work, still working out, and still being an incredible step mom to Tay and Bray!" Heather has been filming seasons 6 and 7 of Netflix's Selling Sunset during her pregnancy, and joked on Instagram last month that her baby boy will be making his "debut" in the upcoming two seasons.
