Justin Bieber will eventually go off the rails, says veteran musician Kid Rock.

The 42-year-old singer says the Canadian superstar, 19, will eventually succumb to the darker temptations that are associated with celebrity.

Speaking to America's GQ magazine Kid Rock explained: ''It's just a matter of time before someone puts a huge line of cocaine in front of Bieber and he's going to be like, 'Yes! This is f**king awesome!' ''

Kid Rock also lamented the pitfalls of enjoying success too young, referencing Britney Spears' highly publicised breakdown a few years ago.

He added: ''Poor girl. Turned into a space cadet. That dead stare, just f**king like someone stole her soul... ''

Hollywood actor Channing Tatum recently discussed how he worries for Bieber's wellbeing.

He said: ''I do believe that whatever age you become famous, you end up staying that age. I worry about Bieber, man. That kid's wildly talented. I hope he doesn't fall down into the usual ways of young kids because it' so hard for someone to be responsible when they're not asked to be.

He continued: ''We're not asked to do things ourselves. You have someone there with a coffee. 'You want food? I'll get you food.'" Watch Bieber perform at the Billboard Awards last month below:
