They're both blond, have sparkling blue eyes, the same nose and lips.
They are not twins, or even brothers.... Incredibly, they are father and son.
Jamie Oliver proudly posted a picture of his son Buddy Bear on Twitter, saying:
"Buddy at 1 year old I think I might be the dad!! Dead ringer or what."
The celebrity TV chef then delighted his fans with a picture of himself (right) when he was the same tender age.
Jamie's wife Jools gave birth to the little boy in September last year.
The couple were already parents to three daughters, Poppy Honey, nine, Daisy Boo, eight, and two-year-old Petal.
Jamie was overjoyed and in shock when he welcomed his first son last year.
"It's a baby boy guys !!! I'm shocked. "We're all very happy, mum was amazing and both are well and happy x4 kids!! what?!"
