We felt the time was right to open up the boundaries, and say to all of America, regardless of your age, whether you're 2, whether you're 100, regardless of what you believe your talent is - juggling, magic, singing - this is the show you can enter. It's as simple as that.

I was so tired, wasn't having fun any more, and wasn't sure if I wanted to do this any longer. So I turned my phone off and sorted my head out. It was the opposite of a breakdown really, it was a break-up - I got rid of all the idiots, realised my job was supposed to be fun, and got on with my life.
