Writing in her UK magazine column, Katie was responding to Charlotte’s comments about the former model last week.
Charlotte, 28, said of Katie: “She’s weird, she’s so cold. I think she’s a robot, or maybe an alien. A really, deeply odd person.”
In true Pricey style, Katie didn’t hold back in her response, saying: “She must have a record or something coming out and needed to mention me to get some headlines.”
Mum-of-four Katie, 35, then admitted she is a little bit different, insisting you need to stand out these days.
She said: “If you’re quiet, boring and simply a little bit plain, you tend to drop off the radar. Just like she’s done. So you need to say something controversial about someone else – just like Charlotte has about me.”
The businesswoman then took a swipe at Charlotte’s career, implying that it isn’t what it used to be.
“These days, I only seem to see pics of her performing in pubs – wearing strange outfits with dishevelled hair – instead of the stadiums she used to fill.”
Speaking of her own career, Katie also revealed that she’s signed a new deal with her book publishers.
She said: “I’ve signed a new four-book deal with Random House. I’ve been working with them for 10 years and together we’ve sold over 5 million books!
“I’m already working on a new autobiography. Those who’ve done wrong by me, watch out. My fans know I always tell the truth in my books!”
