The 34-year-old German, who is married to singer Seal, was described by judges as the total package.

They said her business acumen, with her Victoria's Secret contract and her own line of shoes, jewellery and confectionery, added to her appeal.

Judges said: "That body. It has made grown men cry, editors sigh and fellow models fume, but when all is said and done, Naomi Campbell is one of the sexiest models of all time."

French-born Marks & Spencer model Noemie Lenoir, 28, came next at 13.

Kate Moss, 30, was 18th. Judges praised her "on-camera comfort with her body, whether waif or womanly".
