Liam Payne’s ‘erratic behavior started ramping up’ after girlfriend Kate Cassidy left Argentina: report

Liam Payne reportedly began acting haphazardly in the days leading up to his tragic death.

Payne’s “erratic behavior started ramping up” after his girlfriend, Kate Cassidy, returned home to Florida on Oct. 14, just two days before the former One Direction member fell from a hotel balcony in Argentina, a source close to the influencer told People Tuesday.

“Like you could see from the Snapchat videos, he was a different person around her,” the insider shared, referring to Payne’s posts about his “lovely day” in Buenos Aires prior to his death.

The photos and videos showed Payne and Cassidy chatting, posing for selfies together and appearing to have a good trip together in Buenos Aires, Argentina.

The source also told the outlet that Cassidy, 25, “had been super supportive” and “stood by him” amid his “legal drama” with ex-fiancée, Maya Henry.

The insider was referring to Henry issuing a cease-and-desist –– just days before his death –– to Payne after she claimed he would repeatedly contact her and her family members.

Reps for Payne and Cassidy didn’t return Page Six’s requests for comment.

The “Strip That Down” singer and the model began dating in late 2022, and she has frequently been by his side up until his death. She traveled with Payne to Buenos Aires to attend his former bandmate Niall Horan’s concert on Oct. 2, and they ended up staying for two weeks.

However, Cassidy explained in a TikTok video shared two days before Payne’s death that she decided to leave the South American country, while he stayed back.

She did not provide an explanation as to why at the time, but her friend previously told The Post that he “begged” her to stay with him, and they got into a “heated” exchange over her wanting to return home.

“He was really unhappy about that,” the friend claimed. “He made sure she knew that.”

The pal continued saying that Cassidy is “devastated” and “hasn’t stopped crying” since she heard the news.

“She’s not alone,” the friend added. “She’s responsive to me and our other friends. We’ll all help her however we can.”

Cassidy spoke out about the tragic loss in an Instagram Story shared Friday.

“Thank you for all of the kind words and love that has been sent my way. I have been at a complete loss,” she wrote at the time. “Nothing about the past few days have felt real. I ask and pray that you’ll give me the grace and space to navigate this in private.”

“Liam, my angel. You are everything. I want you to know I loved you unconditionally and completely. I will continue to love you for the rest of my life. I love you Liam,” she emotionally wrote before concluding with the angel number, 444.

The influencer was later seen running errands with two of her friends in Florida on Sunday. She dressed casually and kept busy by chatting with her friends.

Cassidy joined several other of Payne’s family members and friends –– including all of his One Direction bandmates –– who have released statements mourning Payne’s sudden death.

Payne died after he fell from from the third floor balcony of his room in the CasaSur Palermo Hotel on Wednesday, Oct. 16. He was 31.

The “Teardrops” singer died from multiple traumas that led to internal and external bleeding, the National Criminal and Correctional Prosecutor’s Office previously confirmed to Page Six.

Officials have not revealed if the fall was intentional or accidental, nor have they released an official toxicology report. However, Page Six previously confirmed that there was alcohol and drugs found in his hotel room.

Sources told ABC News on Monday that Payne had substances including cocaine and crack in his system at the time of his death. He also reportedly had benzodiazepine –– which is a depressant –– and “pink cocaine” –– which is a recreational drug that commonly combines methamphetamine, ketamine and MDMA.

Payne had previously admitted to struggling with addiction and dealing with mental health issues.
