JLS have revealed that they are often shocked by the behaviour of their fans’ mums.

The UK boyband, who last month confessed their guilt over the effect they have on their teenage audience, told the Daily Star that it’s often their older fan base who are the worst behaved during signing sessions.

JB said: “They use their daughters as scapegoats saying ‘Can my daughter have a pic with you?’ and then they get right in there, seriously, hands down your pants, front and back. They don’t care.”

Aston also recalled an incident when an older fan got a little too touchy-feely: “This woman put her hand on Oritsé’s bum – not just on his bum, she properly went in through his boxers and up.”

Oritse added: “Yep, it definitely happened, she was in. I was so shocked, I still can’t believe she did that.”

The quartet, who are currently in the middle of their 4th Dimension arena tour, released their official Sport Relief single, ‘Proud,’ yesterday.
