Jessica Alba, 25, was crowned the world's sexiest woman by readers of the FHM magazine in the UK. FHM editor, Chris Bell, said: "She's a talented, successful and beautiful actress who clearly has sex appeal that translates worldwide. Jessica will be celebrating her 26th birthday this week as the sexiest woman in the world."

Alba, the 'Sin City' star could beat the British glamour model Keeley Hazell and 'Desperate Housewives' star Eva Longoria, who were chosen for second and third place respectively. Brazilian supermodel Adriana Lima came fourth, Scarlett Johansson fifth, while Angelina Jolie finished in eighth position. Last year's winner 'Pirates of the Caribbean' star Keira Knightley surprisingly dropped to 12th. Another big surprise was that Britain's Prince William's ex-girlfriend 25-year-old brunette Kate Middleton has jumped from 94th place to 25th. But actress Sienna Miller, 25, had the biggest fall as she has dropped down from 12th place to 45th. Britney Spears, 25, is back in at 54, after falling out of the list last year.

Congratulations, Jessica and Happy Birthday!
