JLS have revealed that they have been forced to cut back on their on-stage stunts for their current tour.
According to the Daily Star, JLS member Marvin Humes said: "We are saving all the stunts because some of the venues we're playing on this tour couldn't withstand exactly what we wanted to do."
"We are looking at flying over the crowd in the arenas and having fire. We're leaving the back flips to Aston, though, because I'm too tall."
Speaking about their upcoming performance at the Brits, he said: "We have Justin Timberlake's choreographer coming over, so we'll have a brand new dance routine. There won't be any more of the heart-pumping moves."
