Liam Payne's girlfriend releases heartbreaking letter to 'best friend and love of her life' after his death

Liam Payne's girlfriend has released a heartbreaking letter to her 'best friend and love of her life' after his death.

The former One Direction member died after falling from the third floor balcony of the Casa Sur Hotel in Buenos Aires, Argentina, on 16 October.

Influencer Kate Cassidy had travelled to the South American city with Payne as the pair attended his former bandmate Niall Horan's concert before the 25-year-old travelled back to the US just days before his tragic death.

Having previously released a statement following his death, she penned a message to her late boyfriend on Instagram.

Cassidy wrote: "L, 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."

Adding photos of the pair throughout the relationship, she continued: " Your energy was contagious, lighting up every room you walked into. 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.

"A few weeks ago, we sat outside on a beautiful evening manifesting our lives together. 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 444.' 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 444."

Cassidy also included a black-and-white photo of the handwritten note from Payne which reads: "Me and Kate to marry within a year/engaged & 2gether 4ever."

A preliminary autopsy has since revealed the singer had died from multiple traumas and 'internal and external haemorrhage', with his father Geoff visiting the South American country and identifying his body.

Following the 31-year-old singer's death, tributes flooded in as fans gathered to pay their respects around the world, former One Direction members spoke out and his friends and family have also released heartbreaking statements.
