This is quite the playdate!
Neil Patrick Harris and partner, David Burtka, took their adorable, life vest-clad twins, Gideon and Harper, for a playdate on the high seas with some very famous company -- Elton John, his partner David Furnish and their son, Zachary.
While the babies are still a little too young for any actual playing, it was a nice outing for their parents. Bauer Griffin snapped photos of NPH and Burtka boarding Elton's yacht in St. Tropez, with the babies in tow.
Here are a couple shots of the ridiculously cute kids and their dads, go here for some more!
