Robbie Williams says he is constantly fearful of losing his music career.

The singer will release his eighth album 'The Heavy Entertainment Show' on November 4, but it seems he worries about his longevity.

Speaking to the Guardian, Williams quipped that he is scared he'll end up working at his mother's flower shop in the future to pay the bills.

He said: "I'm neurotic and I find things to worry about, and if there's nothing to worry about, I make something up.

"When we got put together in Take That, we were told it wasn't going to last, you'd be lucky if you got five years.

"Even during the sort of imperial phase of my career, I'd be thinking, 'Is it stopping now?' I'm 25 years in now, but I'm still sort of waiting for the rug to be pulled from underneath me, for it all to be put back in the box and taken away from me, and for me to be sent back to Stoke-on-Trent: 'See, you're right, this ultimately what you wanted, because you wanted to sabotage this, be found out for the charlatan you are, and you have to and work for your mum at the flower shop'.

"So I think, underneath everything, that's what's propelled me forward, and also made me terrified at the same time.

"Not that working for my mum in the flower shop would be a terrifying prospect, it's just that my life's better now."
