JLS singer Aston Merrygold has revealed that his band mates have nicknamed him “skinny bum”.

Aston said the nickname stuck after the boys saw him getting changed after a recent concert.

“We normally jump straight into the showers after a show.” Merrygold told the Daily Star. “I jumped out naked and was waving my bum at the lads, messing about.

“They’ve nicknamed me ‘Skinny Bum’ ever since. They won’t stop calling me it.”

As for other nicknames in the band, Aston added: “We call Oritse ‘Hancock’ because of his superhero-sized willy, Marvin ‘Incredible Hulk’ because of his big muscles and JB ‘Bananaman’ because [he wears] yellow.”
