Despite their party boy reputation, One Direction prepared for their sell out shows in Dublin this week by drinking tea.

Thousands of screaming fans packed into the 02 arena in Ireland’s capital for the first of their two shows in Ireland.

Niall Horan, Zayn Malik, Liam Payne, Harry Styles, and Louis Tomlinson played their opening sell-out show in Dublin last night and the boys requested boxes of tea bags, milk and kettles in their dressing rooms, as their management have imposed a party ban until after their show.

The party list also contained Irish favorites like Jameson whiskey, but the band won’t be touching these until after the show.

The band are currently in the middle of 117 concerts for the Take Me Home tour.

On Monday Niall Horan arrived home to Ireland ahead of the rest of the band to catch up with his friends and family in Co. Westmeath.

"I'll get to catch up with Niall briefly –but there'll be no taking him to dinner or anything," his mum Maura Gallagher told the Irish Independent.
