The duo were gripped in a rather amusing, clothes-throwing row in Tuesday’s episode of the soap.
EastEnders fans are convinced that Kat Slater and Karen Taylor will end up as best friends, despite their dramatic showdown in the launderette.
Viewers were left in stitches when the two Walford residents started throwing clothes, and insults, at each other across the room.
The duo become embroiled in a feud after Kat (Jessie Wallace) decided to start a new cleaning business with Stacey Slater.
However, as she and Karen (Lorraine Stanley) attempted to put their differences aside, they squared up in front of the washing machines.
Karen told Kat: “I never had you down as a backstabber, I helped you out yesterday!”
Kat spat back: “Shut up you old tart!”
Viewers took to Twitter to share their predictions for the warring pair, with one declaring that they will “end up being besties”.
Sharing a similar sentiment, another viewer wrote: “Even though Kat and Karen dislike each other, I can see them becoming besties lmao #Eastenders.”
“Kat & Karen beefing by dashing clothes will end up in a strong friendship between them after Keegan gets revenge,” one said, using crying-laughing emojis to share their amusement.
Another said: “Loving the relationship between Kat and Karen In @bbceastenders think if they tried they could be a right funny duo #EastEnders #katandkaren.
“Give it a month, Karen and Kat will best friends #EastEnders,” another agreed.
Kat has been struggling since returning to Walford, as the other residents are still angered that Mo Slater told everybody that she had died in order to raise money to pay off her debts.
The much-loved character was last seen in EastEnders in January 2016 ahead of appearing in spin-off series Redwater.
She made a dramatic return when she sparked a bar brawl after she walked in on a benefit for her own funeral.
Jessie, 46, has played the role of the loudmouth, leopard print-wearing Kat on and off since 2000.
