Theres nothing unlucky about the number 13 for couple Neil Patrick Harris and David Burtka !

This weekend, the pair celebrated 13 years together a milestone they marked with some super sweet Instagram shout-outs to each other.

On Sunday, Burtka wrote, 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.
