Larry Busacca/Getty Images for EJAFElton John, Neil Patrick Harris and their respective partners have bonded over the fact that they all recently became parents: Elton and David Furnish to son Zachary, and Neil and David Burtka to twins Gideon and Harper.  Now, the two clans have come together for a fabulous joint vacation to the South of France, their second such outing in two years.

People magazine has published a photo of the four men and their kids together at a beach club and restaurant in Saint-Tropez, France on Thursday.  It's apparent that the photo was taken on a boat since the kids, who are all nearly two years old, are sporting life jackets.  The families visited the same club together right around this time last year.

Gideon and Harper will turn two in October; Zachary's second birthday is on Christmas Day.
