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

The 'Twilight' hunk has topped Glamour's 50 Sexiest Men poll for the third year running, after fighting off stiff competition from his co-star Taylor Lautner who came second.

The top five was completed by 'Pirates of the Caribbean: On Stranger Tides' hunk Johnny Depp, soccer star David Beckham and 'High School Musical' actor Zac Efron in the list, which was compiled from over 40,000 votes by readers of the magazine.

Editor Jo Elvin said: "Over 40,000 Glamour readers cast their votes in the most hotly contested list of the year.

"And while the 'Twilight Saga' men continue to dominate our Sexiest Men list, Glamour readers have shown they have eclectic tastes to say the least - from silver fox, 50-year-old George Clooney, to a barely legal Justin Bieber. What could it all mean? Don't think, just enjoy."

Scottish actor Gerard Butler, 'True Blood' hunk Alexander Skarsgard, Tron's Garrett Hedlund, Kings of Leon bassist Jared Followill and Britain's Prince Harry completed the top ten, although Harry's older brother Prince William failed to make the list at all.

Other notable inclusions in the poll include Michael Fassbender at number 31, Australian siblings Liam and Chris Hemsworth at 36 and 37 respectively and 'Real Steel' star Hugh Jackman in 50th place.
