Johnny Depp says he's 'ashamed' and 'embarrassed' about the text messages he wrote about ex-wife Amber Heard

• Johnny Depp apologized for text messages he wrote about ex-wife Amber Heard.
• In one text, Depp wrote that he was "disgusted" he had ever been with Heard.

Johnny Depp admitted that some of the text messages he wrote about ex-wife Amber Heard were in poor taste, as he took the stand on Tuesday in his defamation case against the actress.

Depp is suing Heard, claiming she ruined his reputation and career by insinuating she had been the victim of domestic violence. Heard claims Depp assaulted her on multiple times before and during their marriage, which ended in divorce after 15 months in 2016. Depp has repeatedly denied the accusations.

On Tuesday, Depp took the stand and was asked by one of his lawyers to explain the writing style on showcase in some of the text messages that were read in court during the trial.

One of the text messages included a message to his doctor in which he called Heard "as full of shit as a Christmas Goose."

In another text message to Heard's former assistant, after the couple's break up, Depp said he was "disgusted that I ever touched that fuckin' scum."

Depp apologized to the jury for having to read the text messages.

"I am ashamed of some of the references made," he said. "I'm embarrassed."

He explained that at the time, he was in a moment of pain and he "went to dark places."

He said that "sometimes pain has to be dealt with with humor, and sometimes dark, very dark, humor."

But Depp claimed to have learned "from those mistakes."

"You move on and that's how you start to understand your own vernacular," he said.
