JLS' Aston Merrygold was hospitalised after a backflip accident during rehearsals for their 4th Dimension tour.
The 24-year-old singer is famed for performing his signature backflip during performances, but even the most experienced dancer can get it wrong. Aston had to be rushed to hospital during the penultimate rehearsals for the tour when he landed on his head while trying to execute the move.
"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," JB told the Daily Mirror.
"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."
The pint-sized singer suffered another accident recently, when he almost drowned on the set of their new music video.
Aston and the rest of his bandmates kicked off the first night of the tour this week in Liverpool. Check out the pics from the show in the gallery below.
