Johnny Depp's legal counsel has rested their rebuttal case in their client's $50 million defamation trial against Amber Heard, NBC News reports.

Depp made his way back to the stand on Wednesday after his four days of testimony earlier on in the trial. The actor's final witness testified on Thursday morning.

Heard, 36, and Depp, 58, are just a day away from concluding their multi-million dollar defamation court case, in which the latter is suing the Aquaman star for supposedly defaming him in an article she wrote for The Washington Post in 2018.

The op-ed was titled: I spoke up against sexual violence — and faced our culture's wrath.

Pirates of the Caribbean star Depp was not named in the op-ed, however, he believes it falsely implies he abused his former wife.

The Edward Scissorhands star was first to take the stand in the trial, claiming not only that he did not physically or sexually assault Heard but that he was, in fact, the victim in their relationship.

A memorable moment in the trial saw him accuse his former wife of leaving "human fecal matter" in the bed they shared in order to get back at him for arriving late to her birthday party.

He also accused his ex of being responsible for his infamous finger injury. Heard refuted this claim, saying Depp sliced his own finger off at the end of a three-day drug-fuelled bender - an allegation supported by the testimony of Depp's former private doctor David Kipper.

Heard accused Depp of physically abusing her, as well as sexually assaulting her with a liquor bottle.

Her legal team submitted photos supposedly proving that her then-husband struck her multiple times. Some of the pictures were taken after Depp allegedly threw a phone at her.

Yesterday, Kate Moss, who dated Depp for a period of four years in the 1990s, testified via video link, telling jurors that she was not pushed down the stairs by her ex-partner - a claim made by Heard during her testimony.

Closing arguments are still scheduled for this Friday.
