The Chase’s Bradley Walsh was left stunned on Wednesday’s instalment of the game show as a contestant revealed it was her 91st birthday.
A team of Margot, Ria, Tom and Colin faced professional quizzer Jenny Ryan - or The Vixen - for a nail-biting run at a cash prize.
Contestant Margot told the studio at the start of the show that it was her birthday - leaving ITV host Bradley gobsmacked, as viewers at home said the 91-year-old could be the oldest contestant to appear on the programme.
At the start of the programme she said: “I'm Margot, 91 and a psycho-therapist from Maidenhead.”
Bradley said: “Happy birthday Margot. 91. Congratulations. I’ve got to say it’s a thrill to have you here.”
She explained she wrote a memoir of her life a decade ago, noting that she was born in Germany and moved to the east end of London in 1939.
She added: “I’m more surprised than you that at 91 I’m still here” and told she would spend the ITV cash prize on a newfangled television if she came out on top.
ITV viewers took to Twitter to express their surprise, with one writing: “Margot looks better at 91 than I do at 31” as another wrote: “Hope I look as good as Margot at 91!”
A third chimed: “Margot is 91 years old and looks 70, fair play to her” as another social media user said: “Please let me look as good as Margot at 91.”
Another user wrote: “91. She’s gonna be good on history then. She lived through most of it,” as another wrote: “Margot is 91 (at the time of filming)?! Well, I wouldn't have noticed!”
This comes after The Chase viewers were left gutted for one contestant earlier this week, as she missed out on a “well deserved” fortune.
As the final contestant standing, Annabelle decided to play for a whopping £80,000 against Chaser Anne Hegerty.
The “amazing” quizzer managed to make it to the final round too, giving her a final attempt to win the money.
She was the only contestant to make it that far, as three others were knocked out of the running by Anne.
Her final round performance was hailed too, as she answered 19 questions correctly by herself, taking her to 20 points ahead of the Chaser, but Anne caught the quizzer with just nine seconds to go.
The Chase airs every weekday at 5pm on ITV.
