Reception, first dance... (have to say thank you to #anniepsaltiras who was supposed to just be a guest but worked really hard to help us get the @tomford tuxes we loved so much AND she tied the bow ties of several guests that night. Annie is a champ and we love her ❤️) photos by @ambergressphotography (why can't I figure out how to tag @melissamcneeley and @doan_ly ??? Oh yeah, cuz I'm old. 👌)

Last year, the couple celebrated 14 years together and Parsons wrote on Instagram, “I met this guy... 14 years ago today and it was the best thing that ever happened to me, no contest. One of his greatest gifts to me is that he no longer takes me to sing karaoke. Also, I believe this was a selfie with an actual camera, as our phones couldn’t do that back then hahaha!”

#sagawards with this guy! 🍾❤️😁🇺🇸
