Speaking to The Evening Standard, Katie confessed that she is still sleeping with estranged hubby Alex and believes that Pete, who she described as “evil”, is secretly still in love with her.
The glamour girl, 32, also admitted that she regrets a few of her multiple cosmetic surgery procedures.
She said of Alex, who is still living in her Surrey mansion: “We’re separated. Yeah, he still comes to the house but we’re not together.
“Do I go and f*** Joe Public or do I go and f*** an ex? Can anyone here tell me that they’ve never f***ed an ex?
“We are still friends, we are adult and amicable… It’s completely different from Pete.”
She then went on to talk about ex-husband Peter’s recent anger over a burn their daughter Princess suffered, making the astonishing claim that his fury was all down to feelings he still harbours for her.
Katie explained: “I wish you could see the burn. It is tiny and not painful. She was with my mother and sister in Klosters and I asked them to put her pyjamas in the sauna so they would be warm and cosy for her when she went to bed.
“She must have followed my mum in and caught her arm.
“If you knew what went on over on Pete’s side of things, it is pure evil. He’s probably still in f***ing love with me. That’s the problem. There’s a thin line between love and hate.”
Infamous plastic surgery enthusiast Katie also admitted that she sometimes regrets going under the knife.
She revealed: “I like my old nose. If I could get it out the cupboard and put it on, then I would. [I got it done] because every surgeon I stood in front of and said, ‘Right, if you could change anything about me, what would it be?’ always said my nose.
“I thought: ‘Oh, why not? It’s not a major thing.’”
Katie is set to divorce Alex later this month after just one year of marriage.
