Amber Heard will stand by trial testimony until 'dying day'

Watch: Amber Heard will stand by her testimony

Amber Heard has insisted she will stand by her testimony from her defamation trial against ex-husband Johnny Depp until her 'dying day'.

Speaking in her first interview since losing the multi-million dollar defamation case against the Pirates of the Caribbean star, the actor addressed the toll the trial had taken on her.

In an interview with NBC's Samantha Guthrie for Today, Heard was asked if she stood by her testimony where she recounted abusive behaviour from Depp.

She said: “Of course, to my dying day I will stand by every word of my testimony.”

Heard also discussed how the trial had affected her mental wellbeing: “This was the most humiliating and horrible thing I have ever been through. I have never felt more removed from my own humanity. I felt less than human.”

The Aquaman star also commented on the reaction on social media to the trial: “I would not blame the average person for looking at this and how this has been covered and not thinking that this is Hollywood brats at their worst. But what people don’t understand is that it is actually so much bigger than that. This is not only about our first amendment right to speak.”

Following a six week trial in Virginia, a jury found that an op-ed Heard wrote for The Washington Post about being the victim of domestic abuse defamed Depp.

Depp was also found liable for defamation after one of his former lawyers called Heard's allegations a "hoax".

The Ed Wood actor previously lost a similar case in the UK where a British court found that claims that Depp was a "wifebeater" were "substantially true".

Heard is set to appeal the ruling while Depp celebrated the jury's outcome and praised the support of his fans, some of who camped outside the court during the trial.
