Justin Bieber has been given a stern warning by his mentor Usher, who told him not to "f**k up" his success, in a teaser for the teen star's new 3D film 'Believe'.
The 'Beauty and a Beat' singer was given a dressing down by the R&B crooner - who had mentored him alongside his manager Scooter Braun - following his wild antics and mischievous behaviour.
"When I first met you I told you, you could have all of this, if you believe in it. Now it's happened, don't f**k it up," Usher tells Justin in the short video clip.
The 'Scream' hit-maker isn't the only one to try and offer his protege some wise words of advice as Justin's elders, including famed producer Rodney Jerkins tells the 20-year-old to "stay humble", try and be the best person he can be and not to ''fall off that wagon''.
Justin's mother also makes an appearance, but chooses to take the maternal approach by gushing about her son.

She tells him: "Justin, I'm so proud of you and you are turning into an amazing young man.''
It doesn't seem as though the 20-year-old has been listening to the wise advice of his mentors considering his string of controversies which include, turning up two hours late for concerts and spitting on his own fans.
'Believe' - which will be released in the US on Christmas Day - is set to give fans an insight into Justin's life through a series of concert footage and behind-the-scenes action.
