Robert Pattinson has been named the world's sexiest man.

The 'Twilight' hunk has topped Glamour's 50 Sexiest Men poll for the second year running, after fighting off stiff competition from other actors starring in vampire-based productions.

The hunky trio were rivalled by 'The Vampire Diaries' star Ian Somerhalder, who was voted third in the survey, proving that women can't get enough of men with fangs.

Glamour's acting editor Charlotte Duck said: "Women are attracted to vampires because of the element of danger that comes with them. They are the ultimate bad boys - and women want to tame the beasts."

The list - which was compiled from over 50,000 votes by readers of Glamour.com - also included many shocks, with many attractive stars being placed further down the list than in previous years.

Johnny Depp dropped from second place to sixth, while soccer star David Beckham slipped from fourth down to 21st.

Hollywood legend George Clooney only reached position 35 on the list, while Leonardo DiCaprio, Keanu Reeves and Jude Law- who have scored highly in the survey in recent years - did not even feature.
