The pregnant star, who is now expecting Kieran's baby, did however admit that she must have been in "cuckoo land" when she married her second hubby, Alex Reid, so soon after her divorce with Peter Andre.
Speaking on C5's The Wright Stuff, Katie said: "I admit, when I split with Pete and I met Alex, that was a month or so - that really was a rebound, an absolute rebound.
"I didn't know the person I was marrying, which is clear. I don't know why I married him so quick, I was in cuckoo land.
"I must say, with Kieran I did have a break. I knew what I was doing - this is no rebound at all but the Alex was. He's The One - I'm not doing any more big meringue dresses!"
Katie added: "I fall in love quick and that's it, I believe I love."
Earlier this week, Katie admitted that she is having "the worst pregnancy" during an interview on ITV1's Daybreak.
Reconfirming this today (20 June), she added: "It's the worst pregnancy ever. I have to take loads of iron, otherwise they have to give you that transfusion don't they?
"I've been sick, I've got sciatica, I weigh 11 stone. I just wanna crunch ice, I just hope I don't lose my veneers."
