EastEnders viewers couldn't believe their eyes on Friday, when they caught a glance at Kathy Beale's dating app profile.
The Walford legend hasn't aged a day since she appeared in the very first episode of the BBC soap back in 1985.
But when fans learned her true age on Friday evening, many were left in disbelief.
After signing up to a dating app, her profile revealed how old she truly was and fans were not expecting it.
While this is a discovery that has come up a few times before in the past, some viewers still weren't away that Kathy was "older than she looks".
As her grandson Peter Beale adjusted her age to 45 on her profile, fans were stunned to learn her real age was 70.
Unable to believe Kathy was this age, many fans took to Twitter to check if they had got it wrong.
As some claimed they believed it was a lie, others simply couldn't contain their shock.
One fan asked: "How the f**k is Kathy 70?! I honestly thought she was in her 30s!!"
Another agreed: "A lot of stuff in #EastEnders is completely unbelievable but Kathy being 70 years old?! I'll have what she's been drinking please, Merlin."
A third said: "Kathy is 70? Bloody hell Ian looks more like 70 than Kathy."
Meanwhile, a fourth wrote: "Is Kathy really 70?!"
This was echoed by another viewer who tweeted: "Kathy is 70?!"
The comments kept coming too, with several fans unable to believe it.
Some viewers were aware of this though, and were surprised to realise others did not know the fact.
Kathy is definitely 70 years old, while the actress who plays her Gillian Taylforth is 65 years old.
EastEnders airs Mondays at 8.05pm, Tuesdays and Thursdays at 7.35pm and Fridays at 8.30pm on BBC On e.
