Amber Heard's attorney, Elaine Bredehoft, broke down in tears as the final day of her client's high profile trial came to an end, a bystander has claimed.

On Friday, Heard's legal team delivered closing arguments, as did attorneys for her ex-husband Johnny Depp, who filed a $50 million lawsuit against the Aquaman star over a 2018 op-ed for The Washington Post, in which she said she was a domestic abuse survivor.

While Depp was not named in the article, his lawyers have argued that it was obvious she was referring to the actor. Heard has countersued for $100 million.

During televised proceedings at Virginia's Fairfax County Circuit Court, the former couple directed a slew of allegations at one another, with a number of claims centering around domestic abuse.

Both have denied one another's allegations of violence.

The final day of the trial saw lawyers for both sides drive home their points on why the jury should rule in favor of their respective clients, following six weeks of testimony from the stars themselves and a packed roster of witnesses.

A man using the Twitter handle @jamesfromcourt, who has been in and around the court during proceedings, took to Twitter several hours after the jury started their first day of deliberation to reveal that he saw Bredehoft in tears.

Responding to a tweet from somebody who said that the lawyer "looks like this trial has broken her," @jamesfromcourt wrote: "Late after trial, before the jury went home, #ElaineBredehoft left for the bathroom crying. We all felt terrible for her. After she came out, we tried to make her smile. I hope it helped."
