The mother-of-five couldn't resist making fun of her failed marriages while chatting about today's news that Rupert Murdoch is engaged to Jerry Hall. Talk turned to pre nuptials, legal costs and financial settlements in the case of divorce.
Katie laughed: "It cost me money to get married and more to divorce! I still haven't learned my lesson. At the end of the day, if you're happy, money isn't everything. I know it helps. It's not always about sex either. If you get on with someone, have banter, have a laugh."
She then added: "I'm so good at giving advice and rubbish at taking my own!"
When asked if Katie was annoyed to pay out money after separations, she joked: "It does but I can earn it again!"
She also said: "People look at my CV. My CV looks shocking. Five kids. Three dads. Three marriages – but I'm a good person!"
Katie split from first husband Peter Andre in 2009. They have two children together, Junior and Princess. Her marriage to second husband Alex Reid ended in 2011 after just one year. She's now married to third husband Kieran Hayler, the father of her youngest kids Bunny and Jett.
She's also mum to son Harvey, from her relationship with Dwight Yorke.
