Robbie Williams believes that as he gets older he has begun to turn into his father.

The ‘Angels’ singer is going back on the road this month for his ‘Take The Crown’ tour, and has found that his physical preparations aren’t coming along quite as easily as they used to.

Speaking to The Sun newspaper, Williams said: “There’s no getting away from it, the big 4-0 isn’t far away.

“My back is f***** and I am stretching every day to make sure I’m in shape for the tour. I’m well aware I have gone a bit ‘dad-sized’.’

The Take That star also compared his younger physique with that of a certain One Direction heartthrob: “There was more of a chance of me being Harry Styles when I was Harry Styles’ age. I had a similar body shape to him.”

He added:“But nobody tells you that you carry on getting thicker and thicker, depending on your DNA. I am slowly turning into my father.

“I am like a trunk of some kind, it’s definitely not lithe. That’s not the word for it. This shape doesn’t lend itself to the running-man dance, let’s say, or body-popping, any more.

“Regardless of what I eat, or how much exercise I do, nature is taking its course, and I am becoming my old man. I’m fine with that, I just hope the missus is.”
