Justin Bieber refuses to "take orders from anyone" and reportedly had a furious rant at his manager and the director of his new movie.
The 'Boyfriend' hitmaker -- who has caused controversy for antics including partying underage in nightclubs, arguing with his neighbours and arriving late on stage -- has been ordered by executives on his upcoming documentary movie, 'Believe', to be on his best behaviour, but reportedly reacted angrily during a meeting about his conduct.
A source said: "Director Jon M. Chu and his manager Scooter Braun had a sit-down with Justin and laid down the ground rules; no speeding, no spitting, no screaming threats at paparazzi, fans or neighbours, no puffing on funny cigarettes -- and absolutely no problems with police.
"Justin's headstrong and never likes being told what to do, so his first reaction was to remind everyone that, without him, they wouldn't have a movie to release. Then he started ranting and raving that he's tired of people bossing him and calling the shots -- so he won't be taking orders from anyone."
His team are said to be desperate to keep the star on the straight and narrow because so much is at stake with the film.
The source added to the National Enquirer magazine: "Huge money's on the line because his last film, 'Never Say Never', earned upwards of $100 million."
