Justin Bieber Cops Attitude, Arrogant Taped Deposition

Justin Bieber was grilled for 4 1/2 hours last week, as part of a deposition by the lawyer of a photographer who is suing him and his bodyguard, Hugo Hesny.

TMZ obtained video from the deposition, in which the pop star is defiant, refusing to answer some questions, copping an attitude with others, and even cursing at a court reporter when asked to speak up.

During questioning, he was asked about on/off again girlfriend Selena Gomez, mugged for the camera and said he, not Usher, was responsible for his success.
