Argentinian authorities are continuing to investigate the death of Liam Payne — and they’re planning to speak with his grieving girlfriend Kate Cassidy, who left the country just two days before the One Direction star’s death.

The Post has learned that authorities have reached out to Cassidy and asked her to provide a witness statement to aid the investigation.

Authorities confirm to the Post that Cassidy is not under any suspicion of wrongdoing, but they hope that she can add context to what happened to the 31-year-old crooner during his fatal visit to Buenos Aires.

“She’s going to help in any way she can,” said a friend of the 25-year-old influencer. “She wants the right people to be brought to justice, and if that takes her answering their questions, she’s going to do it.”

“Obviously, there’s no reason for her not to cooperate,” the pal continued. “She tried for a long time to help him get clean, and is still haunted by what happened. Anyone who provided drugs to Liam should be prosecuted, she says.”

Payne took his fatal fall off the hotel balcony on October 16, just minutes after he was dragged unconsciously through the lobby.

An autopsy found that the “For You” singer had a toxic mixture of drugs in his system at the time of his death — including crack and so-called “pink cocaine,” which is a mixture of ketamine and other drugs.

Three individuals have been charged by Argentinian police in their investigation into the singer’s death.

They face criminal counts including “abandonment of a person followed by death” and “supply and facilitation of narcotics,” according to the National Criminal and Correctional Prosecutor’s Office No. 14.

The first man accused was Rogelio “Roger” Nores, Payne’s close friend who was with him “on a daily basis” during his stay in Buenos Aires, according to the prosecutor’s office.

A second defendant is Braian Nahuel Paiz, a former waiter at the CasaSur Palermo Hotel. Authorities say that he allegedly sold cocaine to Payne during his stay, but he denies any wrongdoing.

The third man, described only as “a drug supplier,” is said to have also provided the crooner with drugs on two different occasions on Oct. 14 — two days before his fatal plunge.

As authorities try to bolster their case against the three men, they are hoping that Cassidy can fill in the blanks of what she knows about Payne’s two-week stay at the hotel.

“She’s happy that they’re taking this investigation very seriously,” says her pal. “Because this has devastated countless people, and if she can help in any way, she will do it. It’s the least she can do.”
