Congratulations are in order for Neil Patrick Harris and David Burtka – they're celebrating 13 years together.
Neil posted a rather heartwarming post on his Instagram page to mark the occasion last night, sharing a snap of his hubby and their son, Gideon.
The 43-year-old let his fans know that their anniversary is actually on April 1.
"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. The gifts are never ending (the guy on the right, e.g.).
"Happy Anniversary, @dbelicious. You're the best," he wrote.
Meanwhile, David wrote a post of his own.
Taking to the same social networking site, he captioned an image of Neil: "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."
Neil and David welcomed their twins, Gideon and Harper, back in 2010, before tying the knot in Italy in 2014.
Over the last week or so, social media has been flooded with posts from proud parents as their little ones skip off to school for the first time.
And it seems that celebrities are no different.
Case in point being Neil Patrick Harris: the actor shared a snap of his adorable twins ready to take on the demands of the kindergarten classroom.
Son Gideon and daughter Harper, both five, posed up in front of their family's New York home wearing their academic best for the occasion.
With both little ones sporting sunglasses, Gideon wore grey trousers complete with red braces and navy deck shoes. Meanwhile, Harper went for grey shorts, black boots and a white shirts… all topped off with a bow in her hair.
'Kindergarten fits these two well. #firstdayofschool,' their 43-year-old father captioned the photo.
Neil Patrick Harris has been married to David Burtka, also an actor, for two years. They welcome their twins – born via a surrogate – in October 2010.
This is just adorable!
It's hard to believe that it's been over a year since Neil Patrick Harris said "I do" to his partner David Burtka.
But in honour of the special day, the former How I Met Your Mother actor took to Instagram (because who doesn't nowadays) to celebrate his anniversary.
"One year ago today I had the pleasure of marrying David Burtka."
"I am so happy that I did—he's a truly wonderful man." He also added, "Here's to many more laughs and adventures…!"
The IG snap is just perfect for showing their love and affection!
The lavish wedding took place in Italy – with only a small number of friends and family attending the romantic ceremony.
Sir Elton John treated Neil and David's twins to a performance, followed by the newly married pair dancing to Kelly Clarkson's hit, A Moment Like This.
"It was nice. It was very small, intimate. Only 45 people were there," Neil told The View shortly after the big day. "I just wanted to be able to say nice things about David, to David, in front of the people who matter most to us…a declaration to share in front of our kids."
