The couple, who have been together for 20 years and married for 10, were seen enjoying a swim in the waters of Mykonos, the island of the winds.
The “Barney” from How I Met Your Mother was captured by photographers diving with a mask and snorkel. The two husbands appeared quite cheerful, with some shots showing them smiling.

In April, the couple celebrated their 20-year relationship, and the actor shared a photo of them on Instagram to dedicate it to Burtka.
In the caption, he wrote: “Our first date was today 20 years ago. Man, how fast time flies… and yet… we’ve shared so many adventures and created so many remarkable memories. If the next 7,300 days are like the previous ones, I’ll be absolutely thrilled. Happy anniversary, David. I love you unconditionally, most of the time.”
The couple married in 2014 and have two children: 13-year-old twins, Gideon and Harper.
