Relations 'strained' between 1D lads

Relations between members of One Direction are strained, a report has claimed.

The British boyband, who formed on 'The X Factor' in 2011, have been following an intense schedule in recent months and while sources close to the band continue to insist everything is fine between the five members - Harry Styles, 20, Zayn Malik, 21, Louis Tomlinson, 22, Liam Payne, 21, and Niall Horan, 21 - Mirror Online has claimed trouble is starting to brew.
