I get so tense I’m often close to puking. We started off on a TV show so I should be at home there, but every time we do telly it riddles me with nerves. I’m petrified from the minute I get in the dressing room to the second we walk out on to the set. I don’t know why - and it’s getting worse.

I just spiral into this one massive bag of nerves. Then, when the next show comes along, it starts again, only worse. Maybe it’s because it feels quite intimate? I don’t like singing in front of small crowds.

In 2013, when we were invited to perform at the American Music Awards, I was in a state about singing a song I was usually comfortable with. Then before we went out, Justin Timberlake was coming off after collecting an award and I remember saying to the lads: “Is that the calibre of people here?” To make matters worse, as he walked off Justin came over to say hello and I was bricking it, nearly swallowing my own puke. I was fine in the end, but it’s draining being that nervous.
