Heard's sister takes the stand in Depp defamation case

Amber Heard is giving evidence for the fourth day in her ex-husband's case against The Sun.

UPDATE 14:45

Amber Heard has finished giving evidence her ex-husband Johnny Depp's defamation case against The Sun.

Ms Heard's sister Whitney Henriquez is now giving evidence in support of Ms Heard's accusations that Mr Depp was violent towards her during their marriage.

Ms Henriquez lived in one of the apartments owned by Mr Depp where he and Ms Heard also lived.

Representing Mr Depp, Eleanor Laws asked Ms Henriquez about an incident on a staircase in March 2015 when Ms Heard hit Mr Depp.

During her evidence, Ms Heard admitted to hitting Mr Depp on this occasion, but only in defence of Ms Henriquez, having remembered hearing a rumour that Mr Depp had pushed model Kate Moss down a set of stair.

Ms Laws then suggested that if Ms Henriquez had known of Mr Depp being violent towards her sister, she would not have lived in the penthouse next door to him, to which she replied: “It was happening and I chose to live there.”

Mr Depp's counsel then enquired about Ms Henriquez' relationship with her sister in 2015, when they had fallen out due to private pictures of her and Mr Depp's wedding being sold.

Ms Henriquez confirmed that she was asked to leave her apartment after which the sisters did not speak for some time.

Ms Heard's sister continues to give evidence in the High Court in London.

Earlier, Ms Heard finished giving evidence following four days on the stand.

Ms Heard (34), has accused Mr Depp (57), of verbal and physical abuse throughout their relationship, forming the basis of The Sun’s defence of the articile in which they labled him a ‘wife-beater’.

Mr Depp, however, says he was not violent towards Ms Heard, claiming it was she who was violent to him.

During her evidence, which began on Monday, Ms Heard has claimed Mr Depp pushed Kate Moss down a flight of stairs, called the faeces found in the couple’s bed after her 30th birthday “absolutely disgusting” and denied having an affair with Tesla founder Elon Musk.

Today, Sasha Wass, counsel for The Sun’s publisher News Group Newspapers continued her re-examination of Ms Heard, asking the actor about text messages she sent to her mother about Mr Depp.

In the text messages, Ms Heard describes her ex-husband as “a madman”.

The message continued: “I feel like I’m on a very fast train that’s about to explode, but I don’t want to jump off and leave my love behind.

“So I stay on the train, even though I know it’s about to explode.”

Ms Heard explained that when Mr Depp was sober he was “generous [and] loving, he is a remarkable man when he is like that.

“I loved him and I didn’t want to lose that… the other side of him was a monster, but I always held out hope that he would get clean and sober.”

Ms Wass continued by asking about a night in March 2013, which Ms Heard described as the “first peaceful night” having locked Mr Depp out of the house.

Ms Heard told the court that she confided in her mother, Paige Heard, who died earlier this year, because she understand first hand, saying: “My father was violent to my mother growing up.”

Ms Heard continues to give evidence.
