Amber Heard was allegedly arrested for domestic violence against her then girlfriend Tasya Van Ree in 2009, it has emerged.

Her mugshot was taken and she appeared in court the following day.

Heard is currently suing Johnny Depp for divorce claiming, amid other things, that he was violent towards her and threw his iPhone at her, bruising her face.

But the prosecutor declined to take the case further but warned Heard she could reconsider and refile within the two-year statute of limitation period.

It was previously revealed that Heard considered herself married to her Van Ree, before she ever tied the knot with Depp.

While gay marriage was not legal at the time, the couple did everything that would make them as legally close to married as possible.

The two women viewed themselves as a married couple even if on paper the word was not available to them eight years ago.

The now 30-year-old actress went as far as changing her last name to match her photographer love's name.

On March in 2008 in California, the star legally changed her name to Amber Van Ree and stated the reason to do so as they were in a 'domestic partnership'.

Three months later, California started issuing marriage licences to gay couples but that was halted later that year, with gay marriage not legal in California again until 2013 and across the US until 2015.

Secret wedding: A source said the two women held a private ceremony three years after Amber changed her name to celebrate their love

A source told the Mirror that the couple went on to have a private ceremony in 2011 in New York, when same-sex marriage was legalized there but did not make it legally official.

The couple asked the special few who attended the wedding to keep the wedding a secret, the source said.

Amber, The Mirror reports, did not need to divorce her partner because of their legal status but did petition to change her name back in 2013 and it was granted the following year three months after she and Johnny got engaged.

Bruises: Amber claims the 52-year-old actor attacked her while drunk and high over last weekend - and it was not the first time that he had done so

It was Amber's continued friendship with her former wife that reportedly led to Johnny's alleged explosive anger at the star.

Amber claims the 52-year-old actor attacked her while drunk and high over last weekend - and it was not the first time that he had done so.

Amber said in documents submitted to a Los Angeles court on Friday that she 'truly feared my life was in danger' more than once during the couple's 15-month marriage.

The star successfully argued she need restraining order against her estrange husband, who she says smashed up there home and threw a phone at her leaving her battered and bruised.

The Rum Diaries actress also begged the judge for protection for her Yorkshire terrier, Pistol, who was a gift from wife Tasya.

While Amber claimed she feared what the actor would do to the pooch, Los Angeles Superior Court Judge Carl H. Moor determined there was 'an insufficient showing of need to protect the pet dog.'

In her declaration of petition for a restraining order, seen by DailyMail.com, Amber said she this was not the first time Johnny had been abusive.

Amber, who has filed for divorce, said: 'Johnny has a long-held and widely acknowledged public and private history of drug and alcohol abuse. He has a short fuse.

'He is often paranoid and his temper is exceptionally scary for me as it has proven many times to be physically dangerous and/or life threatening to me.'

She also said: 'During the entirety of our relationship, Johnny has been verbally and physically abusive to me.

Asked for protection: The star (pictured Janurary) successfully argued she need restraining order against her estrange husband, but failed to get the same for her dog Pistol, who was a present from ex Tasya

'I endured excessive emotional, verbal and physical abuse from Johnny, which has included angry, hostile, humiliating and threatening assaults to me whenever I questioned his authority or disagreed with him. I live in fear that Johnny will return to (our house) unannounced to terrorise me, physically and emotionally.'

Giving credibility to reports that Johnny has had an issue with Amber's continued relationship with her ex, Amber said of Friday's alleged attack was started over 'something that was untrue' that he was obsessed about and his 'demeanor changed dramatically' and 'became extremely angry'.

Johnny did not appear in court but his legal team have dismissed the domestic violence claims as nothing more than a cash grab - the couple have no pre-nup.
