Neil Patrick Harris [1] and David Burtka hit the open water with friends on Saturday. The couple, who tied the knot [2] in 2014, caught some rays while laying out on a yacht and took in the beautiful ocean view as they sailed away. In addition to hanging out with friends, Neil showed off his shirtless [3] body as he and David went for a swim in the crystal-clear sea. While it isn't clear if their twins, Harper and Gideon [4], joined them, these two certainly seem to be enjoying their time together.
