Cate Blanchett says it was love at first sight when she met her husband.

'The Hobbit: An Unexpected Journey' actress has been married to screenwriter Andrew Upton for 15 years, and she has revealed they got engaged within weeks of meeting each other as they knew they were perfect for one another.

In an interview with Britain's The Sun newspaper, Cate said: ''The most romantic moment in my life was meeting my husband. Love at first sight? Yes, it was.

''He proposed two weeks after we met. A straight, old-fashioned proposal.''

The 43-year-old Australian beauty - who has three children, Dashiell, 11, Roman, eight, and Igantius, four, with Andrew - didn't have time for a honeymoon after getting married because of her busy Hollywood career, so instead made a romantic pact with her husband.

She added: ''We didn't have time for a honeymoon because I had to leave Australia for England to film 'Elizabeth'. It meant that I was on my own, in places like Newcastle. So we thought we'd stretch it out over the next 50 years in instalments.

''We have taken it when we can. I did the film 'The Talented Mr. Ripley' in Italy and only worked about two days a week during a Roman summer, so that was a fantastic place to catch up on romance.''
