Liam Payne’s girlfriend, Kate Cassidy, is still ‘in shock and disbelief’ following his unexpected death at 31 years old. A source tells ET that she’s trying her best to process the loss, leaning on loved ones, and focusing on ways to honor Liam’s life and memory. Kate returned home just days before the former One Direction star’s fatal fall from a Buenos Aires hotel on Oct. 16, two years after the couple first met in 2022.
