Members of The Wanted band have been barred from drinking alcohol in their dressing rooms.
The group comprises Tom Parker, Nathan Sykes, Max George, Siva Kaneswaran and Jay McGuiness.
"We have been banned from having beer in our dressing rooms. So we have gingerale and all that kind of stuff instead," dailystar.co.uk quoted George as saying.
"They want us to look after our voices and stay out of trouble from now on," he added.
