Dem Babies are two adorable little leprechauns!

Mariah Carey and Nick Cannon's charming 2-year-old twins Moroccan and Monroe celebrated St. Patrick's Day with mom and dad Sunday, all donning green garb and getting into the shamrock spirit together.

Of course, the American Idol judge took to Twitter to document the festive day, warning friends not to "drink and drive" and sharing her leprechaun name (Clover O'Rainbow) with all her followers.

"Roc and Roe celebrate the day! #DemBabies" the mother of two captioned the precious pic of her twins, in which Roc is sporting a green hat and polo, while Roe rocks a "queen of green" crown.

"Dem babies still celebrated," Mimi posted just after 10 p.m., sharing a pic-framed Instagram shot of the entire family partying together. 

Based on Carey and Cannon's smiling faces (we don't think Nick's grin could get any bigger), it looks like the cute quartet had a blast spending quality time together.

Talk about making family memories worth more than a pot o' gold!
