The singer tragically fell to his death after falling from the third floor balcony of the Casa Sur Hotel in Buneos Aires, Argentina, on 16 October.

An investigation has been launched into his death by prosecutors with a post-mortem examination reporting he died of multiple traumas and ‘internal and external haemorrhage’.

Since the 31-year-old’s death, fans have held vigils across the globe in memory of the star.

With his family and friends in attendance and his girlfriend Kate Cassidy reported to be there, it is also expected several celebrities will be at his funeral.

Alongside Payne’s old One Direction bandmates (Niall Horan, Zayn Malik, Harry Styles, Louis Tomlinson), the music mogul who put them all together, Simon Cowell, is expected to be in attendance.

The band, who took a hiatus in 2015, released a joint statement following Payne’s death, which read: “We’re completely devastated by the news of Liam’s passing. In time, and when everyone is able to, there will be more to say. But for now, we will take some time to grieve and process the loss of our brother, who we loved dearly.

“The memories we shared with him will be treasured forever. For now, our thoughts are with his family, his friends, and the fans who loved him alongside us. We will miss him terribly. We love you Liam.”

Cowell wrote on social media how he was ‘truly devastated’, ‘heartbroken’ and felt ’empty’ after hearing the news.

He added in his statement: “I always thought the 5 of you in the band as brothers. And regarding their messages today I believe you were. And now Liam, I can see the effect you had on so many people. Because you left us too soon.”

It is believed the funeral today will be held in private, with fans on social media urging others not to show up.

The charges in connection to Payne’s death were announced on 7 November as one of those confirmed had been accompanying the singer in Argentina and is accused of ‘abandonment of a person followed by death’.

A hotel employee and a third person have also been charged with supplying drugs.

The announcement from authorities also ruled out third party involvement and ‘self-harm’ in the singer’s death with some of his devices still being analysed.

He was pictured walking in and out of the Casa Sur Hotel, joining fans in their tributes.

“Geoff paused occasionally to put on his glasses to read the notes written in English and picked up the pictures to kiss them,” Sky correspondent Martha Kelner said.

“He also thanked fans for being there.”

Over on social media, footage of Geoff getting out of his taxi and into the hotel shows fans ‘blocking’ paparazzi from taking photos.

Taking to X, one fan wrote: “Liam’s fans are fighting with the paparazzi to protect his privacy at this time, putting up their hands and backpacks so they can’t take pictures.”

“My heart goes out to Liam Payne’s family during this tragic time; it’s commendable that his fans are standing up against the paparazzi to protect his privacy and show their support,” a second added.

“Heartbreaking situation. It’s great to see fans rallying to protect his family’s privacy during this difficult time,” a third tweeted.

“He earlier visited the morgue to confirm the identity of his son and the prosecutor’s office to arrange for his repatriation to the UK,” she added.

Payne rose to fame on The X Factor alongside Harry Styles, Niall Horan, Zayn Malik and Louis Tomlinson, when One Direction was formed.

Simon Cowell broke his silence in a tribute shared on Instagram last night, saying he felt ‘truly devastated’.

“This is so difficult to put into words right now. I went outside today, and I thought about so many times we had together. I wanted to let you know what I would always say to the thousands of people who would always ask me. What is Liam like?” he wrote.

“And I would tell them you were kind, funny, sweet, thoughtful, talented, humble, focused. And how much you loved music. And how much love you genuinely had for the fans.

“I had to tell you when you were 14 that this wasn’t your time. And we both made a promise that we would meet again. A lot of people would have given up. You didn’t. You came back and within months the whole world knew Liam.”
