Katie Price has no time to work out.

The former glamour model had her fifth child, nine-month-old Bunny, with 28-year-old husband Kieran Hayler last August, but she luckily managed to bounce back into shape without the need for excessive exercise and going to the gym isn't ''a priority'' for her right now because she's focused on raising her family.

When asked how she keeps her figure so trim, the 37-year-old star said: ''It makes me laugh when people ask me how I'm keeping fit.

''When am I going to find time to work out with five kids and all my animals to look after? I do keep saying to Kieran, 'Shall we both start doing the gym together soon?' But we just haven't got it in us. We're so busy, involved in doing the house, me working. It's not my main priority.''

Katie - who has five children, horses and various other animals to care for on her farm - also revealed she relies on Kieran for healthy eating advice because he's a qualified personal trainer.

Speaking to the new issue of OK! magazine, Katie said: ''If I need tips on nutrition, diet or exercise, I'll ask Kieran - he's a qualified personal trainer. But it's not on my list yet. And I'm not on a diet either. I just eat what I want. I'm busy.''

Katie is currently busy working on another attempt to crack the pop charts, and has hinted it's her most ambitious music yet.

The brunette beauty - who released a duets album entitled 'A Whole New World' with first husband Peter Andre and attempted to become the UK's 'Eurovision Song Contest' entry in 2005 - said: ''I am (planning to put out more music) but you'll have to wait. It's not just one bit of music though. You have to wait and see!''
