Troubled Justin Bieber storms out of deposition hearing in Miami after lawyer quizzes him over ex-girlfriend Selena Gomez


Much-maligned pop star Justin Bieber stormed out of his deposition hearing in Miami after being quizzed over ex-girlfriend Selena Gomez.

The 20 year-old singer was called to the sunshine state's city for a formal hearing on Thursday regarding a lawsuit that claims he instructed his bodyguards to confront a photographer who was then assaulted.

But events reached breaking point when he was repeatedly questioned by a lawyer about his former relationship with the brunette actress.

According to celebrity website TMZ, the lawyer interrogating Bieber started asking if Selena was present during any incident involving fights with photographers.

Bieber's lawyer, Howard Weitzman, objected - considering the question a deliberate attempt to provoke a response from the star - but he persisted.

In protest, Justin and his representative left the courtroom with the pop star shouting: 'Don't ask me about her, do not ask me about her!'

TMZ report that the pair later returned to complete the four-and-a-half hour deposition, but that relations remained tense. In a series of barbed responses Bieber allegedly said: 'What is this, 60 Minutes?' and later: 'OK Katie Couric, what's your question again?'

The Believe hitmaker is being sued by Jeffrey Binion, who claims one of the star's minders choked him and stole his camera equipment in June 2013, and is to be quizzed by the paparazzo's lawyer next week in a videotaped session.

It has been claimed Justin ordered his bodyguard to seize Jeffrey's memory card after he tried to snap a candid picture of the teen heartthrob leaving a recording studio.

Binion is suing both the pop star and his bodyguard, saying he suffered bodily injury, pain and suffering, mental anguish and incurred medical expenses following the incident.

Meanwhile,it seems that Justin may have other personal relationships to consider - namely, with a new sibling.

His mother, Pattie Mallette tweeted on Thursday night that she wanted 'more kids'. Taking to the micro-blogginf site, she wrote: A baby looks good on me eh? (Yep still Canadian). #iwantmorekids!' as she posted a picture of herself with a baby.

Earlier this month, Pattie joined her son Justin to celebrate his birthday in the Bahamas.

The All That Matters singer splashed out thousands of dollars to fly his friends and family to a secluded beach resort on the Caribbean island of Eleuthera, where villas cost a reported $4,275 a night, to celebrate turning 20 last Saturday. .

The break comes after concerns for Justin's welfare since his move from Calabasas, Los Angeles to Atlanta to pursue his hip hop career.

According to reports the 'Boyfriend' hitmaker no longer has any real rules or plans, with insiders claiming much of his time is spent smoking marijuana and consuming sizzurp, a cocktail made with Sprite and medications codeine and promethazine.
