Later, Tarek shared video on his Instagram Story with scenes from the party, including a moment where Taylor joked with the pair as she raised her birthday cake above her heads a number of times.

"In true Taylor fashion, giving us a dang heart attack with that cake," he wrote, in part, in the caption.

Guests enjoyed mocktails and homemade pizza at the family-filled event, which also included a few different areas to pose for pictures.

After several commenters noted that Heather appeared in more of the photos than Taylor, Tarek addressed the matter, writing, "Just so everyone knows this is a joint post. I chose all of the photos in this post. So to all the people being awful to my incredible wife, be a better person…."

The Selling Sunset star posted a sweet Instagram message to her stepdaughter in honor of her birthday in late September.

"Happy birthday beautiful girl! 🤍🫶🏻 I can’t believe you are 13 today!" the realtor began in the caption to a carousel of photos featuring the mother figure and her stepchild snuggling, bonding and enjoying blended family time together.

"I’ve watched you grow into a smart witty, confident, sweet but strong willed young lady," El Moussa continued. "You have such a huge heart and you are truly unstoppable. I love you so so much and I love being your bonus mom. 🤍."

On Saturday, the Flipping El Moussas stars’ baby boy turned 8 months old, and they shared an adorable photo and video of him to commemorate the milestone.

Heather shared a video of Tristan holding a giraffe toy on her Instagram Story alongside the caption, “I cannot believe my little love is eight months old!!”

In the video, the Selling Sunset star spoke to her son, saying, “Cutiebear is 8 months old today, yes you are,” before panning away from Tristan in his stroller toward her dog, Bugz, and then back again. “8 months old, big boy!” she added.

Tarek reposted the clip on his own Story with a heart emoji and the message: “Happy 8 months sweet boy!!”
