The “Aquaman” actress, 34, said Depp encouraged her to sign the agreement before their February 2015 nuptials at the behest of his sister, Christi.

“He said it was Christi [who wanted it], that he didn’t want that, that he trusted me,” Heard testified in Depp’s explosive libel trial in London.

Wearing a cream blouse and dark pencil skirt, Heard told the court that she was never interested in the actor’s money and “would sign whatever I needed to sign.”

But the pair became involved in a heated fight in January 2015 when Depp accused her of having an affair with a co-star when they were discussing the agreement.

“There was an argument in a hotel room in Tokyo that resulted in Johnny kneeling on my back and hitting me on the back of the head,” she testified.

She alleged that Depp hit her in the hotel room and that “everything else proceeded in the closet.”

But she ultimately never signed the prenup before they wed the next month, as the documents were left on Depp’s “team’s” desk and “no one did anything.”

“That is why we didn’t need to have a fight about it because he wasn’t claiming it was something he wanted,” Heard testified. “He said time and time again that he would tear it up, that the only way out of this was death.”

Heard, who finalized her divorce from Depp in 2017, walked away from their split with $7 million, which she donated to charity.

Heard’s testimony marked the first day she has been on the stand in her ex-husband’s libel case against The Sun over allegations of domestic violence during the pair’s tumultuous relationship.
