Katie Price believes marriage is for life.

The 38-year-old former glamour model - who is married to Kieran Hayler and was previously wed to Peter Andre and Alex Reid - was stunned to learn a high percentage of people support the idea of a two-year contract, where they can decide whether or not to stay with their spouse because she is an ''old romantic'' who never planned to get divorced.

She said: ''Two of the people I was with I got married one was in five weeks, the other was six months. I'm still with the one five weeks, the six months one I didn't even get to two years.

''But I'm an old romantic. When you marry someone it's for life. You plan to be with them for life, you don't plan to divorce. I know I did but I had my reasons.

''So many people are commitment-phobic, there would probably be more marriages if you did have [a two-year lease].

''But for me the thought of walking down the aisle, being with that person for life - that is just the fairytale for me.''

Despite believing in marrying for life, Katie admits she had reservations about being wed to Alex - who she split from in January 2011 less than a year after they tied the knot - but still ''went for it''.

Speaking on UK TV show 'Loose Women', she said: ''I did think 'What am I doing?' but I just went for it.''

Katie - who has son Harvey, 13, from a relationship with footballer Dwight Yorke, Junior, 11, and Princess, nine, with Peter and Jett, two, and Bunny, 23 months, with Kieran - insisted it is important to make an effort within a marriage.

She said: ''I think when you're with a person you grow with them. Of course you're more relaxed, it's not a bad thing. But, I still make an effort - try and keep them on their toes.''

And though she disapproves of the idea of a two-year marriage contract, she can see financial benefits.

She added: ''If you've got a get out clause you haven't got to go down the divorce thing, and then lawyers would be out of a job.''
