Neil Patrick Harris has found the perfect role for the two new little bundles of joy in his life: party props!

The 'How I Met You're Your Mother' star took a break from rehearsing for his upcoming Tony Awards hosting gig to stop by 'The Late Show with David Letterman' and share a few quirky but adorable glamor shots of his baby twins.

The 'Smurfs' actor and partner David Burtka are currently raising their 8-month-old twins, Gideon and Harper, in New York City, where, it seems, celebrity daddies celebrate Cinco De Mayo by pasting fake Frida Kahlo-inspired unibrows on their babies and taking photos of them for the family calendar. Yep, calendar!
