"Happy Birthday, David," he wrote alongside a photo of Burtka and their twins Harper and Gideon. "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"
The Lemony Snicket's A Series of Unfortunate Events star and his husband celebrated their 13th anniversary in April. The actor shared a photo of Burtka and son Gideon on Instagram to mark the occasion.
"Thirteen years and one day ago, I crossed paths with the guy on the left," he posted. "The adventures have never ceased. The love has never waned. The gifts are never ending (the guy on the right, e.g.). Happy Anniversary, @dbelicious. You're the best."
