Sin City star Jessica Alba has been crowned the sexiest woman in the world by readers of FHM magazine in the UK.
Alba stars in Fantastic Four: Rise of the Silver Surfer this summer
The US actress, 25, beat glamour model Keeley Hazell and Desperate Housewives star Eva Longoria to take the title.
"She's a talented, successful and beautiful actress who clearly has sex appeal that translates worldwide," said the magazine's editor, Chris Bell.
Last year's winner, Pirates of the Caribbean star Keira Knightley, dropped to 12th place.
But it is fellow Briton Sienna Miller who recorded the biggest fall.
The actress, who recently won critical acclaim for her portrayal of Andy Warhol's muse Edie Sedgwick in the film Factory Girl, plummeted from 12th place last year to 45th.
