Forgetting the words to my own songs on stage. I’m a very good mumbler of my own songs. You’d be surprised how few people notice – if you smile and do it confidently, they’re none the wiser.

When I was 11, I went down a water slide and my bottoms didn’t go with me. Everyone saw my bare white butt.

When I concentrate, I put my thumb in my mouth. I once did it during a really important meeting when asked a question I didn’t know the answer to. When I left the meeting my friend said: “What did you put your thumb in your mouth for?” I didn’t know I’d done it.

I was in Kensington Gardens and this couple stopped me and said: “Hey, could we get a picture? I said: “Sure.” I put my arms around their shoulders, and they looked at me and said: “No, can you take a picture of us?”

I’m afraid of the dark.

“You’re not in Busted any more.” I successfully auditioned to be in Busted and then a couple of days later I got a phone call to say that I was no longer needed as they were going to keep it as the three of them. But it ended up being OK.

A pair of Back to the Future shoes. They were auctioned off for Michael J Fox’s Parkinson’s charity, so I bid and I won. I am a huge fan of the films and if there was ever a pair of shoes I should own, it was those.

On stage with my band.

Complicated, chaotic, messy.

Seeing my kids getting older scares me.
