JLS may be busy in rehearsals for their busy summer of touring, but according to Aston Merrygold one member "can't be bothered" to go for the high-octane energy. 

Speaking to the Daily Star newspaper, the singer explained that all of the on-stage acrobatics are left up to him because bandmate Marvin is too lazy:

“I’m the only one who will do them. Marvin can actually backflip as well but he can’t be bothered so he leaves it to me."

He also revealed that the guys have been working very hard to put together an unmissable show for their fans and added:

“We’ve been putting in the hours to get this new show just right and there’ll be some surprises as well as elements from the Outta This World tour.”

JLS's new single, 'She Makes Me Wanna', will be released on July 24 and you can listen to it here:
