Heather Rae Young shared the “first glimpse” of her baby boy after an ultrasound appointment.

“This was my very first time seeing him since I found out his gender so it was so special 🥰,” the “Selling Sunset” star, 34, told her Instagram followers Tuesday. “I love ultrasounds because I get to see him and hear his heartbeat.

“As a new mom-to-be these things give me flutters in the best way,” she continued. “But it’s also nerve racking because you want to make sure your baby is healthy and in the best condition possible.”

Young added that the “ultrasound went great,” gushing, “Getting a little peak [sic] at our boy made my week 💙🙏🏻.”

The Netflix personality’s co-stars sweetly commented their support.

Young announced last month that she and her husband, Tarek El Moussa, are expecting their first child together. The little one will join the 40-year-old “Flip or Flop” alum’s two kids with ex-wife Christina Haack: Taylor, 11, and Brayden, 6.

In July, the couple revealed the sex of their upcoming arrival with blue confetti cannons.

“Can’t believe we’re expecting another baby BOY El Moussa in the family!!!” El Moussa wrote via Instagram at the time. “The moment I saw the blue confetti I couldn’t believe it.”

The “Flipping 101 with Tarek El Moussa” star added that while he incorrectly predicted Young was pregnant with a daughter, she knew the sex “deep down.”

The couple wed in October 2021, one year after their engagement.
