“Yes. It is true I slapped her. But I didn’t abuse her,” Jorge Arantes, 52, told The Sun on Wednesday night.

Arantes, who according to the outlet is a former journalist and ex-drug addict, also showed no remorse for his admitted actions.

“I’m not sorry for slapping her,” he said from outside his mother’s house in Porto, Portugal.

Rowling, 54, was married to Arantes from 1992 to 1995, and they had a daughter, Jessica Isabel Rowling Arantes, in July 1993.

The author is currently married to Neil Murray, who she wedded in 2001.

Rowling revealed her experience with domestic abuse and sexual assault in a lengthy essay she published Wednesday where she defended her controversial views on transgender issues.

“I managed to escape my first violent marriage with some difficulty, but I’m now married to a truly good and principled man, safe and secure in ways I never in a million years expected to be,” Rowling wrote.

“However, the scars left by violence and sexual assault don’t disappear, no matter how loved you are, and no matter how much money you’ve made,” she said.

Although she does not detail the assaults or identify her attacker, she mentions how her “perennial jumpiness is a family joke” as a result.

Arantes told The Sun that he hadn’t read Rowling’s essay.

“I don’t care about it. What she says is up to her. It’s her responsibility, not mine. There was not ­sustained abuse,” he said.
