It is no secret that Katie and Perez DO NOT get on, and she has been busy winding him up after the crowd were heard chanting "get Perez out" during last Friday's live show.
Today, Katie has thanked fans for their noise, as she believes Perez is feeling very uneasy about it.
Writing in her column for The Sun from the CBB house, Katie addressed viewers and said: "The great British public will be pleased to know that thanks to your roars of, 'Get Perez Out' during the last eviction, the fool was so afraid of the crowd he applied plugs to his ears and cheese to his nose.
"I can say with some certainty that, for all his buffoonery, he is scared of you. Well done."
Former Apprentice star Katie and US blogger Perez have been at war for the best part of their time in the house. Last night, the pair were shown having a mega row while taking part in CBB's Big Debate task.
But although Perez seems determined to brand Katie a "bully" and "homophobe" - which she strongly denies - it appears his plan is backfiring.
Having entered the house labelled 'Britain's Most Hated Woman', Katie seems to have swayed public opinion dramatically!
And that's not the only surprise either. Outspoken Katie has formed a close bond with former glamour model Katie Price, who she has openly slated in the past.
Earlier today, Katie H described Katie P as "beautiful"...while also branding her husband Kieran Hayler a "cretin" for cheating.
Backhanded compliment, much?!
