Elton John boarded a yacht in St. Tropez today with his husband, David Furnish, and their young son, Zachary, who was ready for the water in a life jacket. The threesome headed off to a friend's boat docked near the coast of France. David and Elton have been enjoying time on their own luxury vessel this Summer. Elton and David were joined by Neil Patrick Harris and David Burtka, along with their twins, earlier this month, and the two families lounged in the sun and explored the Mediterranean together. NPH and his partner have since parted ways from their famous friends, but it looks like Elton and David's getaway isn't over yet as they continue to relax overseas with other pals like British comic David Walliams and his bikini-clad supermodel wife, Lara Stone.
