The star of Breakfast At Tiffany's topped the survey of Hollywood actresses through the ages, while Angelina Jolie, Keira Knightley and Halle Berry followed her in the second, third and fourth positions.

The poll of nearly 2,000 film fans put Hepburn in first place, citing her perfect bone structure and almond eyes. Jolie was second, although she was a favourite with younger voters, and Kelly was third, reports the ‘Telegraph’.

The survey was commissioned by Sky+ HD.

Nicola Moulton, beauty and health director of Vogue, said: "A great cinematic beauty by definition has to look amazing in motion, not just in pictures.

"Audrey Hepburn is clearly a timeless beauty explaining why she is the nation's choice, though a personal favourite of mine has always been Vivien Leigh - she was not only breathtakingly beautiful but had an astonishingly expressive face.

"Unlike many actresses her expressions never run counter to her beauty, which seems an essential point of her being rather than just a quirk of genetics."
