The “Aquaman” actress, 34, told her mother, Paige, that the star was like “Dr. Jekyll and Mr. Hyde,” according to texts revealed during Depp’s blockbuster libel trial in London’s High Court.

“He makes dad look like a saint when he falls off the wagon,” Heard wrote on March 23, 2013.

Heard on Thursday also described the path of destruction that Depp, 57, left during a series of alleged assaults that she previously referred to as a ‘three-day hostage situation.”

She said that Depp, whom she claimed was on the drug MDMA and drinking heavily during the bender, was “out of his mind” at their rental home, scrawling “messages in paint and blood.”

“When I first opened the door that last morning, there was what appears to be mashed potatoes and gravy or something rubbed all over the door,” Heard told the court.

“I remember there was a bird, which scared me to death,” she continued, adding that it likely flew through a broken window.

Heard said there was “blood, tons of, like, painting, blood on the walls” and raw meat on the floor, as well as “hidden in places.”

“I found raw meat, at first I didn’t know what it was, on the floor,” Heard said. ”

She said when she got downstairs, Depp was playing “death metal, blasting really loud” and she could see “tons of broken glass.”

“There was so much glass on the floor I could barely find a pathway to walk,” she said.

The court heard that Heard previously witnessed violence at home growing up.

Heard told the court that her father, David, “struggled with alcohol and drug abuse issues his whole life.”

“He is an addict and an alcoholic and he was very violent but I love him very much,” she said.

Heard said that reached out to her mom after one of Depp’s alleged benders in March 2015 because she wanted “someone to talk to who might understand first hand how it was.”

“My father was violent to my mother growing up,” Heard told the court. “They loved each other but he was very violent to her until the end… she passed away.”

In other messages from the same evening, the actress told her mom that Depp was experiencing “crazy mood swings,” adding that his “binges are really difficult for me to handle.”

“I feel like I’m on a very fast train that’s about to explode, but I don’t want to jump off and leave my love behind,’ she wrote.

“So I stay on the train, even though I know it’s about to explode.”

Heard told her mom the “Pirates of Caribbean” actor was a “madman” — but insisted he was not physically abusive with her.

“It’s ok mom. He’s not being violent with me. He’s just even raging in general,” she wrote.

The “Justice League” actress, however, denied in court that she was being truthful to her mother, saying she “just didn’t want her to tell my dad.”

“I felt safe to tell my mother, but I didn’t know how my dad would react,” she said. “I had never been in this situation before and I didn’t know if he would react violently … to Johnny.”

Heard, who wed the Oscar nominee in 2015, has accused him of being violent toward her more than a dozen times during the course of their relationship.

Depp has vehemently denied all allegations of domestic abuse, saying his ex-wife was the violent one.

He’s suing The Sun over a 2018 story that labeled him a “wife-beater.”
