Justin Bieber dropped "F-bomb" while being grilled in a lawsuit alleging he had instructed his bodyguard to attack photographer Jeffrey Binion and take his film card.
The 'Beauty and the Beat' singer seemed deceptive during his grilling session, People Magazine reported.
The source said that when Binion's lawyer Mark DiCowden took Bieber to task regarding these attacks, the teen icon stated that he simply couldn't recall the occasions.
The insider said that Bieber appeared to have selective amnesia, used constant facial gestures and dropped the F-bomb during the deposition.
