Happy birthday, papa!

How I Met Your Mother star Neil Patrick Harris shared birthday greetings for husband David Burtka with a sweet snapshot of their 6-year-old twins Harper and Gideon.

“Happy Birthday, David. You’re the most glorious husband/father/person I’ve ever had the pleasure of knowing. My love and appreciation for you is immeasurable. May this be your best year yet! xoxo,” the Gone Girl star, 43, captioned the Instagram image.

Last weekend, NPH took Gideon to his first Yankees game. Meanwhile, David and Harper enjoyed a tea party at The Plaza.

Earlier this month, Harris posted a photo of Gideon playing with Pokémon.

Over the Mother’s Day long weekend, the actor shared a snapshot of the twins and his parents.

The proud papa shared a sweet selfie with the twins over the Easter long weekend.

In March, the Doogie Howser, M.D. star posted a photo of his kids celebrating St. Patrick’s Day.
