Robbie Williams has said that Justin Bieber's list of 'f**k-ups' means that it's inevitable the teen pop star is going to burn out.
Speaking with The Sun, the Take That superstar said he worries whether Bieber is equipped to deal with the obstacles that he is likely to face as a famous popstar, and that his own issues with drugs might be repeated by the Canadian popstar.
"There is a list longer than my arm of f**k-ups," Robbie said.
"It's inevitable that someone like Justin Bieber will hit a hard time. You hear about everybody going, 'You're s**t'. And you go, 'F**k, I'm s**t, I'd better go and do something else'. And it gets to you."
Robbie famously left Take That in 1995 after his problems with addiction spiralled out of control.
The 'Candy' singer eventually conquered hs demons after several stints in rehab, but last year admotted that he does at times have the urge to return to his wild ways.
Bieber's fans were shocked by reports that the singer was smoking pot
Bieber has been in spotlight recently after being pictured apparently smoking a joint.
The controversy upset his hordes of fans, and even led to the Twitter hashtag #cutforbieber, where fans said they would start cutting themselves if he didn't stop smoking.
Bieber used a recent Saturday Night Live sketch to poke fun at himself and apologise for smoking weed.
