Christina, 36, and Ant, 40, hung out by their backyard pool with her kids Taylor and Brayden (who she shares with ex-husband Tarek El Moussa) and their dog Cash.
She shared some of their Labor Day activities on her Instagram Stories.
Brayden, 4, expertly went down the slide and into the pool like a boss. Ant, however, didn't do as well, causing Christina to call him "basic" in the caption to her Instagram Story.
Christina and Ant have expertly thrown shade at each other on social media in recent months.
He called her "rude" after she complained about his work boots being in the house that she described as "stinky" on Thursday, August 29.
The Wheeler Dealers host also got playfully frustrated after Christina kept beating him in a game of rock, paper, scissors at the beach that he posted on Saturday, September 1.
