Williams worried about BieberComment on this story
London - Robbie Williams is worried about Justin Bieber.
The 39-year-old 'Candy' singer is concerned that the 18-year-old Canadian star is too young to deal with his huge success and fame and fears it is "inevitable" the 'As Long As You Love Me' singer will hit a rough patch in the future.
The Take That star, who battled drug abuse and severe depression in the past, told The Sun newspaper: "There is a list longer than my arm of f***-ups. It's inevitable that someone like Justin Bieber will hit a hard time. You hear about everybody going, 'You're sh**'. And you go 'f***, I'm sh**, I'd better go and do something else'. And it gets to you."
Robbie previously admitted he is constantly worried his insecurities will get the better of him and led him to ruin his life.
The singer, who spent several stints in rehab to combat drug and alcohol addiction, and his wife Ayda Field welcomed their first child into the world, daughter Theodora 'Teddy' Rose last September and he credits his family with keeping him on track.
But he previously admitted there is a part of him that will always be "mad for" dangerous narcotics and he'll never get over his urges completely.
He said: "Everything I like is addictive, destructive, or corrosive. Addiction to danger is no stranger to me, it's fashion.
"There's always going to be a part of me that wants to exist in a psychedelic realm. I only did heroin once and never got addicted but there is still a lot of me that is mad for all that."- Bang Showbiz
