There’s a new national holiday you may not be aware of: Family Day. Hosted every year on April 30, it’s the great alignment of Mariah Carey and Nick Cannon’s wedding anniversary and the birthday of their two twins, Moroccan and Monroe. How President Obama hasn’t already signed the paperwork making this an official federal observance, we don’t know.

Mariah and Nick made sure to put their little cuties first by hosting what looks to be one epic birthday party. In a family photo snapped amid the festivities, we see the 3-year-olds surrounded by colorful balloons, wearing a tiara and fedora (respectively), and hanging with the ‘rents.

Thankfully, Mom and Dad got a little one-on-one time on their special day and we don’t think they kept busy with facepaint. In a candid black and white snapshot, a dapper Nick kisses his lady love on the cheek as she grins from ear to ear and hugs a teddy bear.

We can't hear y’all because Our LOVE is too loud!! KKLB,” Nick captioned the photo, using that four-letter acronym that’s special code between the two romantics. A cake in the photo reminds us it’s the couple’s sixth wedding anniversary, pretty much a lifetime together in Hollywood years. Congratulations, Mariah and Nick!
