The lads in Britain's Got Talent group The Mend have revealed that supporting Little Mix on tour has been a lot of fun, but they were surprised at which member was the naughtiest.

Speaking to Yahoo! OMG, the boys explained that 'the quiet ones' are usually the worst and songstress Jade Thirlwall was the embodiment of that statement:

"They were really nice girls. We got along. Jade's the cute, innocent one. But the quiet ones are always the worst. She's the instigator. We did a prank on Little Mix on Jesy and Jade was instigating it like 'do it do it'. She was proper getting [us] in the mood."

The Mend admitted that the prank was putting "disappearing ink on her favourite leggings".

According to the group, Little Mix were the ones who started the pranks war: "They got us first. They trashed our dressing room, lipstick on the walls - wrote our lyrics and changed them to some very rude words."
