JLS have made a rule on their tour stating that they aren’t allowed to nap during working hours lest they incur cruel prank-punishments from their bandmates.

The band is currently on their Outta This World tour and performed in Glasgow last night (November 30). They’re getting used to the long hours travelling and pass the time setting ground rules for a bit of fun.

JB said to The Sun: "No one's allowed to go to sleep during what we call working hours, which is on the bus during the day to and from venues.

"Whoever does, something unpleasant will happen. A dancer fell asleep so we took pictures, it wasn't pretty. The only thing we have promised not to do is shave eyebrows off."
