US actress Jessica Alba has been crowned Sexiest Woman in the World by readers of FHM magazine in the UK.
The 'Sin City' star, 25, beat the likes of 'Desperate Housewife' Eva Longoria, Scarlett Johansson, Angelina Jolie and Girls Aloud star Cheryl Tweedy to the title.
'Pirates Of The Caribbean' actress Keira Knightley, 22, has dropped out of the top 10 after taking the top spot last year.
But it is actress Sienna Miller, 25, who has had the biggest fall. The 'Factory Gir' star has plummeted from 12th place last year to 45th position in the poll.
Footballer Wayne Rooney's fiancee Coleen McLoughlin, 21, is also out of the top 100 after grabbing 45th place last year.
Troubled singer Britney Spears, 25, is back in at 54, after falling out of the list last year.
Bob Geldof's daughter Peaches, in 55th place, and Arsenal footballer Theo Walcott's girlfriend Melanie Slade, in 96th position, are in the top 100 for the first time.
Supermodel Kate Moss, 33, has sneaked into the top 100 at 68 thanks to a late surge from fans who heard that she was set to be booted off the list.
FHM editor Chris Bell said: "Jessica Alba is a worthy winner of this year's FHM title. 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, you can't really get a better present than that."
