Happy Anniversary, David Burtka and Neil Patrick Harris!

On Sunday, the couple celebrated their seventh wedding anniversary. And to commemorate the day, Burtka shared a loving tribute to his husband on Instagram with a photo from their wedding.

"Six years ago today @nph and I got hitched. Thanks for dancing into my heart. I can't believe you stuck around after all these years of me annoying you. 😂," Burtka wrote "You have made my heart complete. Thank you for the best times of my life."

On Sept. 6, 2014, they wed in Italy after getting engaged in 2007.

"Six years ago. Perhaps the happiest day of my life. Since then, thousands of memories. No regrets. Thank you, David, for both creating and rocking my world. I am forever #grateful @dbelicious," Harris wrote.

In April, Harris, 47, and Burtka, 45, who are fathers to 9-year-old twins Harper Grace and Gideon Scott, celebrated their 16-year anniversary together.

"It's been the best 16 years of my life," Burtka wrote in his own post.

"This hasn't been the most romantic anniversary, but it has certainly been one of the most memorable," he added. "There is no one else I would rather have for my Quarentine! Happy Anniversary."

The pair have been socially distancing together with their children and two dogs.
