On Sunday, the How I Met Your Mother star shared a candid shot of the happy couple handsomely dressed while enjoying a laugh.
"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," the 42-year-old actor captioned the charming photo. "Here's to many more laughs and adventures…!"
Harris and the 40-year-old actor-chef were together for nearly 10 years before getting married in 2014 in an intimate ceremony in Italy. The couple are parents to fraternal twins, Gideon Scott and Harper Grace, who were born via surrogate in 2010.
