Neil Patrick Harris let his fans know just how much husband David Burtka means to him. He paid tribute to his “glorious husband” on his birthday, sharing a photo with fans of his six-year-old twins Harper and Gideon.

“Happy Birthday, David,” he captioned the photo.

“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 @dbelicious (sic).”

The couple has been married for over a decade and the sentimental actor marked their wedding anniversary with another special message on Instagram.

“Thirteen years and one day ago, I crossed paths with the guy on the left. The adventures have never ceased. The love has never waned,” he wrote.

“The gifts are never ending (the guy on the right, e.g.). Happy Anniversary, @dbelicious. You’re the best.”

David had his own message for his spouse.

“Yesterday was mine and @nph 13th year anniversary.!! Thank you Neil for being compassionate, adventurous, and an all around fantastic man. I love you more than ever.”

David previously opened up about the couple’s family life since having children.

“Two weeks ago Neil and I were on the couch at 9:45 pm watching TV and we were like, ‘Oh my God! We’ll probably get to bed by 10.30 tonight!’ That was just a joy for us.

“We used to be able to party until 2 am, wake up whenever, eat bad food and it didn’t even matter! Now it’s all rush, rush, rush – every half an hour slot is booked up.

We’re also growing up and getting a little wiser, realizing what is important in life and that is our family.”
