Kate Bosworth's fiancé knew he wanted to marry her before they even started dating.

The 30-year-old actress met her husband-to-be, director Michael Polish, when they worked together in 2011 on the movie 'Big Sur' but they didn't start dating until after she had split from actor Alexander Skarsgard in July 2011.

Even before they got together, Michael had told Kate he wanted to make her his wife because he was so enchanted by her.

Speaking in the new UK issue of InStyle magazine, she revealed: ''I never even dated my husband-to-be. He said to me after just a few weeks, before we were even together, 'I'm going to marry you.' He just knew.''

The couple got engaged in September 2012 after the filmmaker popped the question, and they have started planning their nuptials, although Kate is staying tight-lipped on the details

However, she did tease that her big day won't be conventional, saying: ''I can give you one detail: it's not the norm and whisky will be involved.''

As well as dating Alexander, the 'Straw Dogs' actress was also previously in a three-year relationship with Orlando Bloom and she admits she has learnt from the mistakes of her past romances.

Kate said: ''When you're in it, it becomes habitual and it's difficult to get out of that. You get addicted to the habit. I'm so headstrong and loyal, and that combination will cause me to stay in a relationship far longer than I should.''
