The TV star has blamed second husband Alex - who she split from in January 2011 after 11 months of marriage - for delaying her plans to walk down the aisle with her fiancÃ©, Argentine model Leandro Penna, who she got engaged to in April.
During an appearance on UK TV show 'Loose Women', she said: ''Well it would've been quicker but obviously someone's after more money, so that's why these things take time.''
Although she is annoyed with Alex - who just became a father for the first time after his fiancÃ©e Chantelle Houghton gave birth to a baby girl - the sexy 33-year-old model insists she isn't in a hurry to tie the knot for a third time.
She said: ''This time I'm being very careful and grown up. There's no rush and I am going to do everything properly. I don't want to keep getting married.''
Katie got together with Alex in the wake of her separation from first husband Peter Andre in May 2009.
With the benefit of hindsight, the busty beauty now accepts she only got together with the 'Celebrity Big Brother' winner because she was on the rebound from Peter - with whom she has two kids, Junior, six, and Princess Tiaamii, four.
She said: ''Well the last time was the rebound. I hate to say it but it was. You know when I was with Pete I never thought we'd split up, I thought it was forever.''
Katie also revealed she will partner Leandro on Argentina's racy version of 'Strictly Come Dancing' after her current book tour.
