Singer Mariah, 45, and 34-year-old Nick filed for divorce last year, and have three-year-old twins Moroccan and Monroe together.
But they put their differences aside to make Easter a special occasion for their babies.
Mariah shared a snap of her and Nick looking for eggs with the kids, writing "Happy Easter!!!! #ontheegghunt #NYiswild [sic]."
She previously uploaded another of her making some pretty-looking Easter cupcakes, which no doubt went down a treat.
But the diva didn't spoil her diet too much, later revealing she prepared a gluten-free lasagne for dinner.
She added: "Sounds dull but it's actually good!"
While both Nick and Mariah have both been linked to new partner, neither one of them have confirmed a new relationship.
Speaking previously to E! News, presenter Nick insisted Roc and Roe will always come first in their lives.
He said: "Family is the number one priority. It's always about making sure you make that connection first."
