Justin Bieber has vowed he can't be ''broken''.

The 'Believe' hitmaker insists he is ''strong'' and has a right to ''defend himself'' in apparent response to criticism of his behaviour in a taped deposition - including being rude to a court clerk, admitting to taking anti-anxiety drug Xanax without a prescription and feigning sleep - which leaked online.

He tweeted: ''Love how some people love to twist and justify the horrible action of others. We all have a right to defend ourselves and feel harassed.

''They can't break us. They can't get us down. We are too strong. We love too much. #mybeliebers (sic)''

Justin, 20, gave the deposition in Miami on Thursday (06.03.14) over a lawsuit from photographer Jeffrey Binion, who claims one of the star's bodyguard's choked him and stole his camera equipment in June 2013 on the orders of the pop star.

In the video, the 'Beauty and a Beat' star was seen visibly angry when asked about on/off girlfriend Selena Gomez by the photographer's lawyer.

The lawyer asked: ''Have you ever talked with Selena Gomez and discussed your feelings about paparazzi with her?''

Justin replied: ''Don't ask me about her again. Don't ask me about her again. Don't ask me about her again.''

At another point, the singer laughs at a question, so the lawyer asks if he needs it reading back.

He replied: ''Well, I don't know, Katie Couric. You tell me.''

And later in the footage, Justin is asked to ''look at the film up there'', but replies: ''This is a film? This is a film? You said it's a film. You said watch the film. Is this a film?''

He is asked to list the members of his team, and after naming a few people, including manager Scooter Braun, he dismissively says: ''The list goes on. It continues, for a long time.''

Asked for more names, he adds: ''I don't recall.''

The lawyer then asked how often his team meet to discuss his bodyguards, with Justin replying ''I don't recall'' before closing his eyes and pretending to sleep.
