The 'This Morning' rent-a-gob branded the singer a "boring old woman" who "probably smells of wee", as she appeared on 'CBB' spin-off show 'Bit On The Side' on Tuesday night.
Talking about Linda, she said: "Boring old woman! Probably smells of wee. She is revolting. Her knockers are somewhere near her ankles."
But Katie didn't stop there - she labelled N-Dubz singer Dappy "just revolting", said that Daily Mail journalist Liz Jones "looks like she's walked into patio doors", and claimed that fellow former 'Apprentice' star Luisa Zissman was "perfect for porn".
Take a look at all her views on all the housemates below...
Lionel Blair: "He’s been let out of a care home and couldn’t find his way back!"
Jasmine Waltz: "She is Cruella De Vil, she has the puppies!"
Dappy: "He’s just revolting, such a child! I’m not one for short people, ginger people or fat people."
Liz Jones: "As for her, I’ve never met Liz, she looks like she’s walked into patio doors, a very flat face. Lacking personality."
Luisa Zissman: "When I came out of 'The Apprentice' I was offered a part in a porn movie, Luisa would be perfect!"
Sam Faiers: "Bland, magnolia, vanilla."
Linda Nolan: "Boring old woman! Probably smells of wee. She is revolting. Her knockers are somewhere near her ankles."
Casey Batchelor: "She’s pathetic, move on Casey!"
Lee Ryan: "He needs to say what he means, a nasty piece of work!"
Lee and Casey's relationship: "They are like two thick kids at the back of the class!"
Evander Holyfield: "He went in there and had no clue. Things aren’t looking good, such a pity."
Ollie Locke: "Nice chap, rather sweet, he hasn’t made his mind up whether he’s gay or straight…we could tell him!"
Jim Davidson: "I love Jim! Utterly brilliant, best of British! I vote for Jim."
