Robbie Williams shares his greatest fear about his career

Robbie Williams admits he carries a constant worry that everything he has built could disappear in an instant.

The Angels singer has previously spoken candidly about anxiety and nerves around performing, and he has now shared that even after 30 years in the public eye, that underlying fear has never truly faded.

The former Take That member explained that stepping onto a stage still brings intense pressure, made heavier by the expectations that come with decades of experience and worldwide success.

He went on to say that live broadcasts and vast arena crowds leave little room for comfort, joking that a single mistake could quickly spiral into mayhem.

While appearing on Virgin Radio, he said: "I have autocue at the gigs and it is like having a safety wire, I know it but I have had moments on live TV where I have completely forgotten the words and completely forgotten the melody and that's when you realise that the colour of adrenaline is brown!"

Robbie continued: "This is a type rope walk act.... We could fall. "I could cause an international incident at any moment, I could end my career at any moment! And that is the anxiety that I am walking with and talking with at all times."

At 51, the singer has also revealed that impostor syndrome plays a major role in how he views himself.

He said: "It's absolutely insane, my whole career exists on audacity and very little else.

"You know there is some shelves left unstacked at an Asda at Stoke-On-Trent because I am not there and that would be my rightful place."

Despite those doubts, Robbie has just rewritten UK chart history by landing his 16th Number One album.

His latest record, BRITPOP, shot straight to the top of the Official Albums Chart in January, securing his place as the artist with more UK Number One albums than anyone else.

He had already claimed the title for most chart-toppers by a solo act, but this latest release firmly places him ahead of every other artist in British chart history.

Speaking about the achievement, Robbie Williams said: "BRITPOP is the record I’ve always wanted to make, and seeing it become my 16th Number 1 album means everything to me. Thank you to all the fans who have been with me every step of the way. You’ve made my dreams come true.”

In a separate interview with the BBC, he also said: "This is unbelievable. Absolutely unbelievable.

"I've always said my success has been the equivalent of stretching an elastic band from Stoke-on-Trent to the Moon. Well, I reckon the elastic band just got longer, and now it's orbiting Venus.

"It's just sensational what has happened. I feel like the Forrest Gump of pop.

"I'm going to take this week, at least, to remind myself of how lucky I am.

"Because for a while, I didn't get to do that because of mental illness or whatever. But now I am firmly in a place where the garden is blossoming, and I'm just surveying the pastures.

"And, I think that's the biggest achievement, that I can sit in that [moment] and take a deep breath and smile."
