One Direction singer Liam Payne wrote a note to his girlfriend shortly before his death, predicting they would get married within a year, she has revealed.

Kate Cassidy posted a new tribute to him on Wednesday, a week after his death in a fall from a balcony in Argentina at the age of 31.

"A few weeks ago, we sat outside on a beautiful evening manifesting our lives together," she wrote on Instagram.

"I keep your note close, even though you told me not to look at it. It said, 'Me and Kate to marry within a year/engaged & together forever'."

She also posted a series of photos, including one of his handwritten notes.

She added: "Liam, I know we'll be together forever, but not in the way we had planned. You'll always be with me. I've gained a guardian angel.

"I will love you for the rest of my life and beyond, carrying our dreams and memories with me everywhere I go. Forever yours, Katelyn."

Payne had been in a relationship with the US influencer since 2022, and she had been with him in South America in the days before he died.

But when Payne fell to his death on 16 October, Cassidy had already left the country.

'The love of my life'

She started her Instagram message: "I don't even know where to begin. My heart is shattered in ways I can't put into words.

"I wish you could see the huge impact you've had on the world, even as it feels so dark right now. You brought so much happiness and positivity to everyone - millions of fans, your family, friends, and especially me. You are so incredibly loved.

"You are - because I can't say were - my best friend, the love of my life, and everyone you touched felt just as special as I did. Your energy was contagious, lighting up every room you walked into."

She continued: "None of this feels real, and I can't wrap my head around this new reality of not having you here. I'm struggling to figure out how to live in a world without you by my side. Together, we got to be kids again, always finding joy in the smallest things.

"Liam, you had the kindest soul and the most fun-loving spirit. It feels like I've lost the best part of myself. I can't imagine a day without your laughter and love. You brought so much light into my life."

Payne's sudden death led to an outpouring of grief from his family, friends and fans around the world.

His father Geoff is now in the Argentine capital Buenos Aires, and authorities are carrying out tests before allowing his body to be returned to the UK.

They are also reviewing phone, computer and security camera evidence to establish the full circumstances of his death.
