One of the last people to speak to Liam Payne detailed the singer’s “disturbing” behavior in his final moments before he plunged to his death from a third-floor hotel room in Argentina on Wednesday.

A woman named Rebecca was staying at the CasaSur Palermo Hotel in Buenos Aires for a friend’s wedding when she ran into the former One Direction band member in the lobby, she told the Daily Mail in an article published Friday.

“I got to the hotel and he was waiting by the elevator, and it was so clear that he wanted someone to recognize him,” recalled Rebecca, who did not reveal her last name. “There was something a little desperate about him.”

The tourist noted that one of her friends was supposed to get Payne’s suite and the staff were “a little nervous” because he hadn’t checked out yet and it was already 4:30 p.m

Rebecca said she stood next to Payne at the elevator with her friends, and although they recognized the “X Factor” alum, they gave him privacy and didn’t react to his fame.

“When the elevator came, he suddenly said to us without prompting: ‘Yes, I’m Liam!’ I really dragged it out and then said, “Okay, come on guys, get in the elevator with me.” “I love cuddling,” she claimed.

Rebecca said she decided to wait for the next elevator, but a few of her friends drove by with Payne and chatted with him.

“Some of the other girls got in with him, and halfway up he started saying, ‘Oh, you guys are Americans.’ I live in West Palm Beach. I know Americans. You guys are fucking crazy! You guys are fucking dangerous!’” she recalled.

The hotel guest said Payne then grabbed a woman she believed was “with him” and began “fake choking” her.

“Just slightly, but the others found it really disturbing,” she admitted.

Ten minutes later, Rebecca returned to the lobby only to see Payne return with his laptop.

“I have a blind relative and I realized that for some reason he had the laptop set to accessibility so that every time he moved the mouse and hovered over something, the machine said out loud where the cursor was,” said she called back.

“I assumed he was doing it for the attention too,” she continued. “Then he opened his emails and saw one that clearly upset him. “Suddenly he picked up the computer and shouted, ‘Screw it, buddy!’ and started banging the computer on the floor.”

Rebecca said viewers were “really shocked” by the “Story of My Life” singer’s outburst.

“It’s a high-end hotel and his behavior was so out of place – people were just chilling,” she said.

Eventually, Rebecca reached out to the unpredictable socialite to see if he needed help.

“I walked over and asked, ‘Are you OK?’ But he just kind of grunted. Then he said, ‘I used to be in a boy band.’ That’s why I’m so shitty,” she claimed.

Rebecca said she was surprised by his comments and “couldn’t believe” he had said “something like that”.

“There was a lot more swearing and he took the laptop and went back into the elevator,” she said.

Rebecca noticed that a Brit in Payne’s entourage stopped by to apologize for his friend’s bad manners and explained to her that he “just gets high like that sometimes.”

“I wondered what these people had done to him to help him, but maybe they had tried and failed,” she said. “The hotel staff were freaking out and watching him very nervously. I could see one of them was on the phone with security or the police.”

Rebecca described Payne as having dilated pupils, a lack of concentration and behaving aggressively.

“I’ve never done cocaine, but he behaved exactly how I would imagine someone who takes the drug would behave,” she speculated.

Payne entered the lobby a third time while Rebecca was still down there, only this time he couldn’t stay on his feet.

“He came back in, tripped, fell flat on his face and hit the floor,” she said. “The staff came to help him and get him back into the elevator and that’s when I took the last photo.”

In Rebecca’s picture, which she shared with the outlet, Payne was seen chatting with two women while his British friend held the elevator door open for him so they could go back to the third floor.

“It didn’t take long for the police to arrive and at first we thought they were just going to throw him out, but then when the staff started running around like crazy we suddenly realized how serious what had happened was,” Rebecca said .

The shaken hotel guest said some of her friends saw Payne fall from his balcony into the hotel courtyard.

“It was terrible and at first they thought maybe he had just injured himself, but then we saw the body out in the yard and later they brought him out on a stretcher,” she said. “It was all so terrible.”

Payne tragically died on Wednesday after falling from his third floor room at the CasaSur Palermo Hotel. He was 31.

The former boy bander suffered multiple traumas that resulted in internal and external bleeding, the Office of Criminal and Correctional Services told Page Six in its preliminary autopsy report on Thursday.

Emergency physician Alberto Crescenti said Payne suffered a fractured skull and “extremely serious injuries that resulted in his immediate death” and that he could not be revived by first responders.

Page Six confirmed that alcohol and narcotics were found in his room, which was completely trashed after his death.

His former bandmates – Harry Styles, Zayn Malik, Niall Horan and Louis Tomlinson – mourned his loss in a heartbreaking statement on Thursday.

“We have been completely devastated by the news of Liam’s death,” the now-disbanded group told Page Six.

“As time goes on and everyone is able, there will be more to say. But for now, we will take some time to grieve and process the loss of our brother, who we loved very much,” they added.
