Johnny Depp and Amber Heard both emerged with mud on their faces Thursday after a string of witnesses gave unflattering testimony about their union and a marriage counselor called their relationship one of "mutual abuse."

JOHNNY DEPP DEFAMATION TRIAL: AMBER HEARD'S PERSONAL ASSISTANT ACCUSES ACTRESS OF ABUSIVE WORK ENVIRONMENT

It was the fourth day of the civil trial in which the "Pirates of the Caribbean" star is suing Heard for $50 million over a 2018 op-ed she penned for the Washington Post alleging she had been a victim of domestic violence.

Although the piece did not name Depp, his legal team has argued that the professional and personal fallout from the allegations have been immense.

Dr. Laurel Anderson, who treated the couple beginning in 2015, described their relationship as dysfunctional and volatile in a videotaped deposition recorded in late February and played for jurors Thursday in the Fairfax County Circuit Courthouse in Virginia.

"They engaged in what I saw as mutual abuse," she said, as the warring exes watched from opposite sides of the room. "I know she led on more than one occasion and started it."

Heard, 35, admitted to Anderson that she had hit, socked and hurled a can at Depp, 58, in various brawls. She told Anderson that Depp had also smacked her and showed her bruises to prove it, the doctor testified. 

"It was a point of pride to her if she felt disrespected to initiate a fight," Anderson explained.

The clinical psychologist described Heard as having a "jackhammer style of talking" that made it difficult for Depp to a get word in. "He was cut off a lot," she added. 

Anderson said Heard had recounted Depp’s verbal assaults during their sessions.

"Mr. Depp says to her, ‘No one likes you, you’re getting fame from me, I’m falling out of love with you, you’re a whore,’" Anderson read from her notes, adding, "She’s reporting how mean they are to one another." 

Earlier Thursday, the videotaped deposition of Heard’s former personal assistant, Kate James, was played for jurors.

The ex-staffer elicited chuckles form the gallery when asked if she was paid and replied "very poorly." James described Heard as extremely demanding, calling her at all hours and on weekends but refusing to pay her overtime.

James, who worked for Heard from 2012 to 2015, said the "Aquaman" actress as "verbally abusive" to her, her late mother and her sister.

"Her mother was terrified of her," James recalled. "Her poor sister was treated like a dog that you kick."

Heard, she said, would bombard her with text messages sometimes beginning as early as 2 a.m.

During one confrontation over James’s salary, Heard allegedly went berserk. "She leapt up out of her chair, put her face approximately 4 inches from my face. She was spitting in my face, telling me how dare you ask me for the salary you’re asking for," recalled the ex-staffer, who was later fired.
