Heard accused the “Pirates of the Caribbean” star of whipping out his privates while being escorted off the Queensland, Australia, property in March 2015 — telling security, “I need to take a f—ing piss, it’s my house,” according to a witness statement in his London libel case.

“He then went back inside and did it right in front of them to nervous laughter,” Heard said, according to UK’s The Sun. “He said was he was trying to write my name on the walls and carpet while peeing in the house.”

But Depp’s estate manager, Ben King, told London’s High Court he was sure there was no urine in the rental home, where he also found the tip of the actor’s severed finger following a row between the pair.

“I did not see any signs of urine, and I did not smell it, as I would have done had someone urinated around the house,” King said, adding that he returned to the house to “chaperone” a cleaning team and they “didn’t mention anything” about pee.

It isn’t the only message the star is accused of scrawling in bodily fluid in the home — he also scrawled “I love you” on a mirror with blood from his sliced finger.

A lawyer representing The Sun newspaper — which Depp is suing for libel after it dubbed him a “wife beater”— asked King if he was sure there was no pee in the home.

“Amongst all this blood and paint, you say you are sure that there was no urine?” Sasha Wass asked.

“Quite sure,” King replied.

Heard has alleged that Depp slapped and shoved her during a booze-fueled fight at the vacation home — evidence offered by The Sun to show he did beat her.

Depp, who insists he has never assaulted Heard, has accused his ex of severing the tip of his finger when she threw a bottle of vodka at him. Heard claims Depp did it to himself when he angrily smashed a phone against a wall.
