But stripping to their birthday suits for an outrageous shoot has got to be their boldest move yet.
The pop-opera superstars have stripped off and let it all hang out for the cameras.
“We’re five normal young lads. We all go to the gym but we’re not obsessed with having a beautiful body. We just try to stay healthy,” said Jamie.
Clearly none of the lads are ashamed of their bodies, but despite being chart-topping pop stars with thousand of adoring fans, some of the boys reveal that they have suffered from serious body image issues.
“When my rugby career was over, I lost a lot of weight dropping from 18st to 15st.
“Then in Collabro I put the weight back on and when we did the Royal Variety performance people said, ‘Oh he’s gotten fatter since BGT’.
“I made a conscious effort to get healthy again.
“Not for vain reasons, if you’re on stage every night, you just don’t want to eat crap, otherwise you’ll end up getting run down.
“If you are confident in yourself, and you accept what you were born with, then that makes you sexy.”
“I was big as a teenager and I would look in the mirror and not see what was looking back at me. I felt very alone and was very self-conscious and my self-esteem collapsed.
“All I would eat was lettuce and runner beans. I ate just enough to live off but it wasn’t healthy.
“I joined lots of LGBT societies and began to meet more gay people and even felt comfortable enough in myself to start a relationship.”
The group’s debut album Stars hit the top spot and the follow-up, Act Two hit No.2.
Collabro have been shot for the Attitude Awards issue available to download now and in shops on Wednesday, June 24
