Actress Amber Heard once told her acting coach that Johnny Depp would rather “destroy” her than let her leave their tumultuous marriage, London’s High Court heard Friday.

Kristina Sexton testified via video link from Australia that the “Aquaman” star, 34, told her, “Johnny will never let me go,” The Sun reported.

Sexton’s testimony came on the 14th day of Depp’s explosive libel trial against The Sun, who he’s suing over a 2018 article that branded him a “wife-beater.”

He has denied the allegations and blamed all the violence in his marriage on Heard.

Sexton told the court that Heard had said she was “embarrassed” at the idea of bad publicity over her marriage to the “Pirates of the Caribbean” star ending after just over a year, but she “had to leave him,” the newspaper reported.

She said Depp arrived at Heard’s 30th birthday party slurring his speech and had to be propped up.

Before the trial resumed Friday morning, Depp’s lawyers complained that Heard had texted her sister, Whitney Henriquez, 31, while she gave evidence on Thursday, according to the Daily Mail.

Depp’s attorney David Sherborne asked that Heard be barred from using her cellphone while in court. The lawyer further requested that Henriquez be kept out of the courtroom while Depp’s team produced a video clip that shows Heard being violent toward her sister, the paper said.

Henriquez testified Thursday that Heard had never been physical with her.

On Thursday, the UK court heard that Henriquez had begged her sister not to marry Depp due to his violent rages.

She told the court that during a vicious 2015 fight,  Depp had allegedly shoved her out of the way to lunge at Heard, prompting the actress to punch him.

Henriquez said she watched as the “Edward Scissorhands” star then clutched a clump of Heard’s hair as he repeatedly socked her in the face.

The sister had been living rent-free in one of Depp’s penthouses next door to the couple.

Heard took the stand earlier this week and called Depp a “monster” who had threatened to kill her “many times” and once described “carving my face up so no one else would want me.”

During Depp’s turn on the stand, he called his ex-wife a “sociopathic” wine-guzzling batterer, who once severed the tip of his finger with a vodka bottle.

Later today, Heard’s friend iO Tillett Wright is expected to testify by video link from the U.S.

After Depp said he discovered human feces in the couple’s bed in April 2016, the morning of Heard’s 30th birthday, he accused his then-wife and Wright of having orchestrated the vile prank.

Heard has denied the allegations and insisted the sizable pile came from Boo, her Yorkshire terrier.

After the poop incident, Depp said he had decided to divorce Heard, describing it as a “fitting end to the relationship.”
