The controversial blogger gushed about KP during an appearance on Big Brother's Bit On The Side last night.
When asked if he thought Katie had been boring in the house and not involved in drama, he replied: "I never thought Katie was on the fence.
"The Katie Price that I saw in the house was the Katie Price that I knew before I went into the house. I told her yesterday, 'Get this boring idea out of your head. If you think that people think you're boring it's because they are expecting a different person and that's not who you are.'"
Perez, 36, went on to say: "I told her, 'You're being honest and being yourself, and if I saw you getting into fights and drinking and parting in the hot tub, you're a mother of five, you just had surgery. Chill!'"
He added: "Katie is being herself in the most authentic nice way. She is an incredible mum and such an inspiring businesswoman. I love her."
Katie, 36, is one of five housemates in the running to win tonight's grand finale. She'll be up against Calum Best, Katie Hopkins, Keith Chegwin and Michelle Visage.
She became friends with Perez several years ago after meeting him in LA while filming her reality show Stateside alongside then-husband Peter Andre.
