The boys' zone

Grinning, with only a glass of Guinness to spare our blushes, Ronan Keating is the latest naked male pin-up.

The Irish singer is part of a crop of stars celebrating a decade of Cosmopolitan's centrefolds.

So girls, here's your chance to catch actor Patrick McGuinness reclining in a bath full of bubbles and cricketer Simon Jones without his whites.

The sealed section of next month's issue also has TV's Craig Doyle getting steamy in a shower and the England rugby sevens using balls to cover up.

It appears with shots of former centrefolds, including footballer Ian Wright.

Editor Sam Baker said: 'We wanted to celebrate this fantastic heritage with a knock-out anniversary issue and continue to use this fun, sexy feature to attract attention to testicular cancer.'

Cosmo's centrefold began in 1996. For the last five years, it has been used to support the Everyman campaign, which funds research into male cancers.
