NPH celebrates his first wedding anniversary in the CUTEST way

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."
