The celebrity chef, 51, posted a photo to Instagram alongside his 18-year-old son after they spent a morning swimming together in the sea.
He captioned it: "Great morning swimming with this dolphin."
Gordon tagged in Tower 26, a triathlon swimming coaching group, as he posed alongside Jack in matching wetsuits.
Fans were quick to comment on how similar the two men look, with one saying: "Two peas in a pod."
He looks like you so much its incredible the facial expression.
Another said: "Jack looks just like this dad!"
A third added, "Gordon and his mini-me", while a fourth said: "He looks like you so much its incredible the facial expression....such a fine young man."
