Liam Payne‘s loved ones are honoring him on what would have been his 32nd birthday. On Friday, his sister Nicola shared a heartfelt tribute, recalling the time they spent together on his birthday last year, just two months before his death. His girlfriend, Kate Cassidy, also posted a touching letter to Payne. I promise you I will celebrate you extra today, honor your life, and cherish the beautiful times we’ve had. Netflix recently released Building the Band, in which Liam served as a mentor for new groups in formation.
