Jamie Oliver was in a celebratory mood on Wednesday as he marked the birthday of his close friend Richard Herd. Richard has known Jamie since his Naked Chef days, and as such, the celebrity chef shared a then-and-now picture from those days.

The pair posed in similar kitchens, sharing laughs in both images as Jamie held a small drink. In a caption, Jamie joked: "How it started vs how it's going... Happy BIG birthday @richardherd!! We haven't aged a bit, don't you lot think?? Hahaha."

While Jamie and Richard showed off their boyish looks, we couldn't help but notice how much the celebrity chef resembled his son, Buddy.

The father of five's hair was identical to Buddy's, and the star even had a similar facial structure.

Fans were quick to celebrate the post, as one said: "He's still got that loving look in his eyes for you, even after so long. Happy birthday @richardherd. I hope the world is being kind to you."

A second added: "You both look great, like vintage wine... or well-matured cheese," and a third commented: "I can hardly see the difference."

It's not just in looks that Jamie and Buddy have similarities, as Buddy has also been following in his dad's culinary footsteps. He has already authored a cookbook and launched his own cooking show on YouTube titled Cooking Buddies.
