The foursome got together in New York's Bronx Zoo to celebrate Easter, and Mimi shared an Instagram photo of the family on an egg hunt.
"Happy Easter!!! #ontheegghunt #NYiswild," she captioned the shot of herself wearing a pink dress and matching leather jacket.
Her ex, 34, was decked out in a New York Knicks orange sweatshirt and snapback hat. Carey and Cannon's children each wore fierce looks of determination, with Moroccan even sporting a Buzz Lightyear shield while searching for the hidden eggs.
Cannon regrammed the post, adding, "Best Easter Sunday @BronxZoo Roc & Roe had a blast finding eggs all over the Zoo! #FestiveFamily #HappyEaster."
The night before Carey also shared a picture of herself in the kitchen, writing, "Making Easter cupcakes!"
Carey and Cannon are currently living apart, but the America's Got Talent host recently told Us Weekly that he feels their children will still have a great childhood.
"My kids kind of get to experience the both worlds," Cannon said in mid-March. "They get Manhattan and a little bit of Jersey."
Though the pair separated last June, Cannon didn't file for divorce until this January.
