Justin Bieber apparently stormed out of a Miami courtroom on Thursday (March 6) after a lawyer quizzed him about ex-girlfriend Selena Gomez.

According to TMZ, JB sat through the four-and-a-half hour hearing regarding photographer Jeffrey Binion, who claims that Justin had arranged for him to be 'beaten up' last year.

The lawyer is said to have interrogated the 20-year old over a number of things relating to the incident - even asking the singer if Selena was present any any of the alleged altercations.

After bombarding JB with questions, the star's legal rep Howard Weitzman stated he believed hisclient was being "harassed".

The Baby hitmaker then apparently shouted: "Don't ask me about her, do not ask me about her!" - before leaving the civil hearing with Weitzman.

After Justin returned to the courtroom and replied to one question with a simple "yes", leaving the lawyer to ask: "Do you mean yes?", to which Biebs replied: "What the f*** is the difference between yeah and yes?"

Binion's attorney is then said to have presented Justin with a number of news stories, leaving the star to accuse him of 'having an obsession' by searching TMZ for articles about him.

Justin is being sued by Binion after allegedly ordering his bodyguard Hugo Hesny to choke him and steal his camera equipment last June when he tried to get a photo of the teen idol leaving a Miami recording studio.
