JLS star Aston Merrygold was hospitalised after messing up a backflip during tour rehearsals. The 24-year-old singer - who is joined in the band by Marvin Humes, Oritse Williams and J.B. Gill - suffered concussion when he landed on his head while executing the tricky move during the penultimate dress rehearsal for the ‘Beat Again’ hitmakers’ ‘4th Dimension’ tour. J.B. explained: ‘’This show really has been blood, sweat and tears ... and scratches. We’re all injured. One of our dancers slipped a disc, one had a really bad neck injury and one a knee injury. ‘’Then Aston fell on his head which was pretty nasty.’’ Aston added: ‘’It’s been full-on. As well as landing on my head, I busted my knee and J.B. did his, too.’’                  –MM
