Kat Moon – played by Jessie Wallace – has had some jaw-dropping storylines since joining Eastenders in 2000.
But none could be more shocking than THAT infamous plot twist of old...
Yup, we're talking about the 'YOU AIN'T MY MUVVA!' scene with Zoe Slater.
Here's a reminder of what happened:
In another exciting soap twist, Kat is set to discover that, on the same night she gave birth to Zoe, she also welcomed a baby boy.
However the teen mum, exhausted from labour, failed to realise that she'd birthed twins... and her little boy was taken away from her to be placed with another family.
In snippets of the upcoming moment in which Kat finds out the truth, viewers have noticed one major similarity between the two child-reveal scenes...
SHE IS WEARING THE SAME OUTFIT!
Yes, there is such thing as an unlucky top – and for Mrs Moon is the black and red shirt that seemed to bring her all the drama.
One Twitter user - who we can only presume to be the biggest Kat Slater fan known to man – took to the site to express her surprise and excitement at the beady-eyed discovery.
Tagging both Eastenders official and actress Jessie Wallace in the tweet, fan Jessie (@sugganiston) posted pictures of the two scenes side by side, captioned:
“IS IT ON PURPOSE THAT KAT LOOKS THE SAME AS SHE DID WHEN SHE TOLD ZOE SHES HER MUM.”
Even her hair and make-up has been styled the same!
Another Eastender's fan responded:
Neither have responded to the conspiracy tweet yet.
EastEnders airs these scenes on Monday, January 11 at 8pm on BBC One.
