Kate Hudson suffers a wardrobe malfunction as her spectacular green dress clashes with a blue carpet

Her dress was exquisite, her face radiant and her blonde hair prettily chic.

But despite all that, Kate Hudson was still struck by a bizarre - and unexpected - wardrobe malfunction as she arrived at the London premiere of her new movie last night.

The source of the faux pas was a blue replacement for the traditional red carpet; the aggravating feature her dress, a shimmering confection of turquoise green and gold.

Colour co-ordinated they certainly weren't and Goldie Hawn's 28-year-old daughter may well have been left pondering the old adage blue and green should never be seen.

However, if the horror of the clashing carpet did put her off her stride, she certainly didn't show it and was soon arranging her spectacular John Galliano gown, which was heavily embellished with embroidery and tassels, for the cameras.

The appearance of Hollywood hunk Matthew McConaughey, her co-star in new film Fool's Gold, seemed to make her even happier and the pair were soon laughing and fooling around on the blue carpet, which had been rolled out in Leicester Square.

Miss Hudson, who was wearing Bulgari jewellery, happily admitted that she was the latest Hollywood star to fall victim to some clever computer trickery after her cleavage was digitally enhanced on publicity material.

"You've just got to let those things go," she said, "I can't tell you how many magazines I've been on where my eyes are blue. I don't have blue eyes, I have green eyes.

"I don't think it sets a bad example. The examples I set are just how I am with my family and nobody knows that but me, my closest friends and family."

Fool's Gold tells the story of a married couple, played by Miss Hudson and McConaughey, who are almost torn apart by the husband's obsession with the Queen's Dowry, 40 chests lost at sea in 1715.

The blue carpet was picked to tie in with the seafaring theme.
