Dr Hilary Jones celebrated his birthday on Good Morning Britain today.
GMB hosts Ben Shephard and Charlotte Hawkins were stunned that the doctor had turned to work on his big day.
And fans couldn't help believe his age as they thanked him for helping keep everyone informed and calm during the coronavirus pandemic.
Dr Hilary turns 67 today and Ben began the congratulations by saying: "We need to say Happy Birthday Hills."
Charlotte exclaimed: "Happy birthday!"
"Yep, I'm in my prime now," Dr Hilary joked.
"Yes, you're in your prime," Ben said. "How many primes is it?"
"Oh, quite a few," Dr Hilary grinned.
Fans flocked to Twitter to comment, with one tweeting: "Happy birthday fellow gemini. Thanks for keeping us calm and informed during covid 19. Well when you weren't being shouted over that is."
While another shocked viewer commented: "His Wikipedia page says he is 67??? Surely not."
