The couple had initially planned to stay in Argentina for five days to support Payne’s former bandmate, Niall Horan, during his concert on October 2. However, they extended their trip to two weeks. Cassidy later explained on TikTok that she wanted to return to the U.S. because she doesn’t like staying in one place for too long.
Reportedly, Cassidy was eager to reunite with her dog, which frustrated Payne. A source mentioned that Payne didn’t take this well, becoming moody. Cassidy eventually booked her return flight, which only heightened the tension between them. Despite this, the couple shared light-hearted moments on social media, including Payne poking fun at Cassidy for leaving the trip early.
Although there was speculation about trouble in their relationship, Cassidy’s friend insisted they were not in serious danger of breaking up. The couple had been together for two years and were living together.
In the days leading up to Payne’s death, rumors also surfaced that he had been seen with prostitutes, a claim Cassidy had been trying to navigate. After Payne’s passing, Cassidy expressed her sorrow and confusion, asking for privacy while she processed the loss. She later posted a heartfelt message on social media, vowing to love him forever.
Witnesses reported that Payne’s behavior became increasingly erratic after Cassidy left. He was staying at the CasaSur Palermo Hotel in Buenos Aires when, tragically, he fell from his hotel room’s balcony, dying instantly from his injuries. He was 31 years old.
