There's nothing unlucky about the number 13 for Neil Patrick Harris!
The actor marked his and David Burtka's 13-year anniversary with a sweet post on Instagram on Sunday.
"Thirteen years and one day ago, I crossed paths with the guy on the left," the How I Met Your Mother star captioned a gorgeous photo of Burtka with their 6-year-old son, Gideon, in hysterics. "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."
Burtka, 41, also celebrated the milestone on social media, sharing a photo of Harris, 43, posing against a wall.
"Yesterday was mine and @nph 13th year anniversary.!!" he wrote. "Thank you Neil for being compassionate, adventurous, and an all around fantastic man. I love you more than ever."
The couple welcomed twins Gideon and Harper, via a surrogate, in October 2010, then tied the knot in a lavish ceremony in Italy in 2014.
Their adorable family adventures are frequently documented on Instagram, like recent St. Patrick's Day dress-ups and a family vacation in Florida.
