The “Pirates of the Caribbean” star, 57, made the alteration on the glass frame of the painting at the couple’s Los Angeles home in February 2014, according to evidence at Depp’s libel trial in London’s High Court.

The court heard that Depp sent a photo of the graffiti to his then-girlfriend’s sister, Whitney Henriquez, to which she responded, “Well done, my friend, well done.”

“The van Pee painting earns you 20 points in my book,” the younger sister wrote, according to the Daily Mail.

Depp then texted her, “Can’t stand that f–king hovering vulture.”

Heard, who appeared in court Thursday, said that Depp had accused her of having an affair with van Ree during a fight in 2013.

“He wanted me to admit that I was having an affair with, not only Tasya van Ree, my ex-partner, but also a gentleman I hardly knew,” Heard, 34, told the court.

“He had just gotten it in his mind that I had these affairs and he wouldn’t leave until I admitted it.”

The court previously heard that Depp gave “derogatory nicknames” to Heard’s co-stars whom he considered a “sexual threat.”

Heard claimed he came up with “pumpkinhead” for actor Leonardo DiCaprio and “turd” for Jim Sturgess.

The actress is expected to wrap up her final day of testimony Thursday in Depp’s case against The Sun over allegations of domestic violence during the pair’s volatile relationship.
