Attitude Magazine has announced the launch of the first Attitude 100 - The World's Sexiest Men 2013, sponsored by Calvin Klein and the Los Angeles Tourism and Convention Board.

Readers can vote on Attitude's website, with results announced July 18 in London's West End before being published July 26. Attitude editor Matthew Todd says 'Sexiest 100 lists have been around in various formats for what seems like an age now, but never from a gay man's perspective'.
