Jellies and clean socks - One Direction gear up for Dublin gig

Jellies, clean socks and plenty of water - that's what One Direction have requested in their dressing room for tonight's concert at the O2 in Dublin.

The X Factor boyband will perform to 14,000 fans in a sold-out show.

One Direction released their debut single 'What Makes You Beautiful' on September 9. It topped the charts with the biggest first-week sales of the year.

The band is signed to Syco Music.
