Megan Fox named world's sexiest woman
The Transformers star was a new entry in the annual poll, pushing last year's winner Jessica Alba into second place.
TV presenter Kirstie Allsopp made her first appearance at 91, while previous favourites Kate Moss, Jennifer Lopez and Myleene Klass failed to make the top 100.
Other new entries in the list included opera singer Katherine Jenkins, Prince Harry's girlfriend Chelsy Davy and model Agyness Deyn.
Keeley Hazell was the highest-placed British woman, finishing in third position. The top five was rounded out by 24 star Elisha Cuthbert and Heroes actress Hayden Panettiere.
Scarlett Johansson, Cheryl Cole, Hilary Duff, Angelina Jolie and Keira Knightley all finished in the top ten.
FHM editor-in-chief Anthony Noguera said: "This year, after 9.7 million votes from around the world, [the poll] has never been more authoritative.
"Megan Fox is a very deserving winner... From out of nowhere, she's captured the hearts - and fantasies - of British men to capture the number one slot."
