The former glamour model - who married Kieran last year - confessed the part-time stripper has encouraged her to eat better by teaching her how to put together tasty salads.
She told MailOnline: ''I believe in eating healthily and I eat a lot better now. Kieran makes delicious salads for me, I never knew how to make them before and they always tasted so bland but he is really into health and fitness so knows what works.''
However, Katie, 36 - who has two-month-old Bunny, and 13-month-old Jett, with Kieran, as well as 12-year-old Harvey, Junior, nine, and Princess Tiaamii, seven, from previous relationships - still enjoys cooking comfort food for her family.
She explained: ''I love making traditional British dishes like shepherds pie and cottage pie, I don't like chocolate, I am more into savoury treats.
''We are very traditional, every Friday we have an Indian and on Sunday we have roast lamb.''
The brunette beauty - who hit headlines earlier this year after her 27-year-old hubby cheated on her with her two close friends Jane Pountney and Chrissy Thomas - also admitted she is keen to get back to work after baby number five and can't wait to get in front of the camera on some ''sexy'' shoots.
She said: ''Obviously I have been pregnant for two years so I am looking forward to getting back to work. I can't wait to do more photoshoots, it's where I started and what I do best, I miss them but I want to do proper styled shoots, themed ones, that are sexy.''
