Sir Elton John is ensuring his new son Zachary has plenty of play dates on hand - they're vacationing with Neil Patrick Harris and his baby twins in France this week (begs01Aug11).
The How I Met Your Mother actor was one of the first celebrities to congratulate the Rocket Man and partner David Furnish on the arrival of their tot via a surrogate mother in December (10), and invited the couple to bring little Zachary to play with his babies, Gideon and Harper, born in October (10).
And the stars have cemented their friendship this week by travelling to St. Tropez for a sunshine break - Sir Elton, Furnish and their son were spotted arriving in the area on a luxury yacht with Harris, his partner David Burtka and their twins, who were also born to a surrogate.
In a post on his page on Wednesday (03Aug11), Harris writes, "The family and I are having one of the best weeks of our lives."
