Jax Taylor and Brittany Cartwright reunited to celebrate their son's birthday amid their ongoing split — but the dinosaur-themed party didn't quite go off without a hitch.

On Saturday, April 13, the reality stars got together to celebrate their son Cruz Cauchi's 3rd "3-Rex"-themed birthday. All seemed to go well, until the cake cutting. TheirThe Valley co-star Zack Wickham captured video of a rather tragic birthday casualty.

In a video shared to Wickham's Instagram and TikTok accounts on April 14, Taylor, 44, can be seen helping Cruz blow out his candles as Cartwright, 35, holds the toddler above a table. Seconds later, the folding table collapses and the three-tiered white and blue cake with Cruz's name written across it can be seen tumbling to the ground.

In the clip, Wickham claps his hand over his mouth, and most of the other party guests can also be heard reacting, while Taylor and Cartwright can do nothing but look at each other in disbelief and laughter. The Valley star also poked some fun at the moment by editing in a meteor to the video that descends upon the cake.

Cruz officially turned 3 on April 12, and per Taylor's Instagram Stories, Cruz enjoyed "all his favorite things" on his actual birthday, including a lunch of chicken fingers and French fries and a trip to the Aquarium of the Pacific in Long Beach, Calif.

The former Vanderpump Rules stars first announced their separation on Taylor’s podcast, When Reality Hits, in February. They revealed they had been having issues for nearly a year. The couple are also currently appearing together on the first season of Bravo's The Valley, which was filmed before their breakup.

“Marriages in general are very hard, and I've had a particularly rough year this past year,” Cartwright said on the podcast. “Jax and I are taking time apart, and I made the decision to move into another home to take some space for the sake of my mental health.”
