Stephen Deuters, Depp’s now-former righthand man, took the stand in British court and at first denied ever hearing his boss use terms such as “slut,” “whore” or “c–t” — before he was confronted by a text message from Depp doing just that.

“She’s a c–t!!!” Depp texted his assistant, complaining about Heard’s accusations that he was “wasted on something else every night,” the court heard.

Depp is suing the British tabloid The Sun for calling him a “wife beater” in a 2018 article. Heard, his former wife, has said the “Pirates of the Caribbean” and “Edward Scissorhands” star violently assaulted her several times over the course of their short-lived marriage, a claim he denies.

Deuters insisted that he “didn’t have any recollection” of the crude text from Depp and added that he would “certainly not” use such language himself — only to be confronted with an even stronger-worded message he wrote about Heard.

“Sociopathic show pony. Machiavellian overlord. Talentless c–t,” Deuters wrote in one message about Heard in 2016 after she and Depp split, the court was told.

“Good riddance to bad s–t. Yes, I do mean Amber not the Mom, even though she was a devil herself,” he added.

Another text said, “At least the bitch is gone,” the court heard.

Deuters told the court of his foul-worded messages, “I certainly regret that.”

In another text that Deuters sent a pal, the personal assistant wrote, “I’ll have you know it’s on public record that Amber Heard has been arrested for domestic violence before.”

He was referring to Heard’s arrest in 2009 for allegedly grabbing the arm of her then-girlfriend Tasya Van Ree during a fight.

Deuters called Depp and Heard “two people that were in love with each other that shouldn’t have been together.”

The witness admitted he was more of a friend than an employee to Depp and agreed he was “regarded almost as family” by the actor.

Their friendship relied in part on “lavatorial” humor, with Depp calling himself “Shatter” — supposedly a pun on playing The Mad Hatter in the movie “Alice In Wonderland” — and telling his assistant he would “poop on [his] chest,” the court heard.

Asked if his boss found “feces and things like that quite funny,” Deuters admitted, “Yes, I suppose so.”

On the opening day of the trial last week, Depp said in a court statement that he believed Heard may have pooped in the couple’s bed as a prank.

Depp’s texts contained “extravagances and exaggerations,” the former employee said, with the court hearing one in which Depp said he had “hookers and animals” in his hotel room and he needed “to kill a few of the animals for sustenance.”

They were “very colorful, humourous – depending on your humor,” Deuters said of the missives.

The Sun’s lawyer, Sasha Wass, accused Deuters of being part of “a public relations initiative to discredit Ms. Heard in the public eye” and “suggest that she was the domestic abuser rather than your boss, Mr Depp.”

But Depp’s friend denied any conversations he had about her involved “any premeditated gathering of information.”

Wass also noted he was still financially dependent on the star, now as the European president of Depp’s production company, Infinitum Nihil — suggesting it showed his “loyalty to him has been rewarded.

“If Mr. Depp or the brand is damaged professionally, you in turn are damaged financially,” Wass stressed, which Deuters acknowledged was true.

But asked bluntly if he was “lying on oath to save your job and your livelihood,” Deuters insisted, “No.”

He repeated to the court that he never saw Depp use violence against Heard, and would “absolutely not” stand by and allow it to happen.
