April 30 is one of the biggest days of the year — and not just because you can send everyone you know that Justin Timberlake “It’s gonna be May” meme. The last day of April marks not only the wedding anniversary of diva extraordinaire Mariah Carey and her husband Nick Cannon, but also the birthday of their adorable twins, Moroccan and Monroe.  

Don’t ask us the probability of the couple having their babies the same day as their wedding anniversary but such is life in the Carey-Cannon household. And the parents seem to have no problem sharing their special day with their even more special little ones!

“Happy Birthday to Dembabies 3 Years Old! Happy Anniversary to us! 4/30,” Mama Mariah captioned a photo snapped of the family mid-celebration.

In the candid shot we see Mariah and daughter Monroe looking lovely against a background of pink balloons, while Nick and son Moroccan wear matching fedoras. Love that manly pout, Mo!

Back in early April, Nick told TV host Rachael Ray he’d planned a secret location for this year’s “Family Day,” and judging from the family photo we think the surprise was a hit! With balloon art and facepaint, the Carey-Cannons look to have had one heck of a birthday party!

The birthday kids got mini-cars as presents, and while Nick and Mariah didn’t share what they exchanged for their sixth wedding anniversary, knowing these TMI two that’s probably a good thing.
