JLS will be scaling down their reunion tour.
The boyband - which consists of Aston Merrygold, Oritsé Williams, Marvin Humes, and JB Gill - found fame on the UK version of 'The X Factor' in 2009 and ahead of their upcoming UK tour in November, JB has admitted that he now has a "problem with heights" so he cannot do the "crazy things" they used to on stage.
