A Hamptons habitué had some unwanted horseplay, literally, in front of his home this week.

Ralph Destino Jr. — the son of Cartier chairman emeritus Ralph Destino — was readying his Water Mill house for a benefit bash when he heard a truck, a cursing driver and some animals neighing and braying on private Noyac Path outside.

“Ralph went out and saw an 18-wheeler stuck on the road with a dozen horses inside,” our source said. “The truck went up the wrong road and couldn’t turn around.”

With the truck stuck, “Nacho Figueras came roaring up in a Jeep, with his hair flowing like a Ralph Lauren ad,” we’re told.

Turned out the horses were being delivered to the polo star, who’s played at Bridgehampton Polo this summer.

With Figueras’ guidance, the truck finally turned, taking some picturesque plantings with it.

“I’ll pay for everything!” Figueras declared.

He returned Thursday as landscapers made sure things were returned to normal before Destino hosted a party Friday for Scott Diament’s Palm Beach Show Group hosted by Campion Platt.
