Former 'N Sync star Joey Fatone is far from impressed with Justin Bieber's antics on tour in Europe and he has gone public with his feelings, calling the teenager a "douche".

From arriving late to shows and trying to smuggle his pet monkey through customs in German to drug discoveries onboard his tourbus in Sweden, Bieber's European tour has been dogged by negative news headlines and Fatone has now stepped up to offer the Baby singer a few choice words via

The Bye Bye Bye star says, "Don't be a douche. That's plain and simple. You get this bug from the celebrity thing, where you're very on top of the world and everyone's 'yessing' you to death, so you're like, 'I can get away with this. I can do that.'"

Fatone adds, "(That's) not to say that he might be doing anything wrong (sic) - or he might be in the wrong mix of people, in his camp."
