Jax Taylor and Brittany Cartwright came together to celebrate a special occasion.

Their son, Cruz Cauchi, turned 3 on Friday, April 12, and the pair joined forces amid their separation to make sure the little boy had the best birthday weekend.

Per Taylor’s Instagram Stories, Cruz enjoyed “all his favorite things” on his actual birthday on Friday. Taylor, 44, and Cartwright, 35, took him to a California aquarium and he ate chicken fingers and French fries.

Then on Saturday, he had a dinosaur-themed “3-Rex” birthday party with his friends that included a trampoline and tons of desserts, as seen in posts on both reality stars’ Instagram Stories on Saturday.

The former Vanderpump Rules stars announced their separation in February after four years of marriage. They currently appear together on the first season of Bravo’s The Valley, which was filmed before their split.

Cartwright shared a sweet birthday tribute to Cruz on Instagram on Friday, posting a carousel of images of her son.

“Happy Birthday to my sweet sweet beautiful boy! I can’t believe you are 3 years old today, oh how time flies!” her caption read. “I am so blessed to be this amazing little boy’s mother he makes me so proud every single day. Mommy loves you sooo sooo much my Cruzy!! 🥹❤️.”

Taylor shared his own tribute to Cruz on Instagram on Saturday. “Happiest of birthdays to my special little man, mommy and daddy love you so much and we are so proud of you,” he wrote in part.

“You are the best thing to happen to both of us and we love watching you grow every day. I am beyond blessed to be your dad you are the kindest, happiest little boy on the planet you amaze me every day,” he added.
