One Direction lived - and sung - by the motto, 'Live while we're young.'
But they also worked hard and played hard, as Liam Payne spilled this week.
MUST WATCH: Liam Payne spills One Direction's code word game when they didn't want to work
When the work became too much for the teenage heartthrobs, Liam said they had a special codeword, which meant they would drop to the ground a play dead.
'When we didn’t want to go somewhere, obviously we had so many things to do in a day and it was so boring at points, we’d have a code word and we’d all fall to the floor and lie there until everybody went away,' he explained.
'I think that’s the best game we ever invented,' he laughed. 'Yes, those were some grown adults who ran a business once. I don’t know how this worked honestly!'
So what was the password? 'Help me,' he revealed.
Worth around $60 million in his own right, Liam said: 'We’d do it in the middle of TV interviews! It’s like one of those games you have with your friends – if you don’t follow through, you’re the loser in the group so everyone would just do it. So bad! I don’t know how we were a success.'
