The former glamour model - who married cross-dressing cage fighter Alex Reid in Las Vegas in February - thinks she is like an "ugly fat woman" because she tries so hard to please her man in bed.
She explained: "I`m worse than an animal. I`m an extremist in bed. You can say I`m like an ugly fat woman, because they`re the ones they say really try. I`m like one of them, I make an effort.
"I`m not just a lay on your back, open your legs, look at the time, I actually work it."
However, the `Free To Love Again` singer - who has children Harvey, Junior and Princess Tiaamii from previous relationships - admitted she felt like a "lost lamb" when her marriage to Peter Andre broke down last year, as the couple`s joint manager Claire Powell took the side of her ex-husband, leaving Katie with no representation.
She added to The Guardian newspaper: "Pete`s there posing with the kids, doing everything, ah poor Pete poor Pete - I had no one to represent me, I was like a lost lamb, I had no representation to help protect me, nothing.
"Whereas Pete was protected straight away. So that gave him a lead, it was like, `Oh f**k it, let`s pick on Kate`."
