In a statement signed by Louis Tomlinson, Zayn Malik, Niall Horan and Harry Styles they said: "In time, and when everyone is able to, there will be more to say".

The pop star, who found fame on The X Factor in 2010, died after falling from the third floor of a hotel in Argentina, police say.

Earlier Payne's family said they were "heartbroken" as they paid tribute to a "kind, funny and brave soul", after his death aged 31.

"We are supporting each other the best we can as a family and ask for privacy and space at this awful time," they said.

Liam was one of five members of One Direction.

The band's statement added: "We will take some time to grieve and process the loss of our brother, who we loved dearly." and concluded: "We will miss him terribly. We love you, Liam."

Harry Styles, former One Direction band member shared a photo of Liam on Instagram, saying that he "lived wide open, with his heart on his sleeve".

"The years we spent together will forever remain among the most cherished of my life.

"I will miss him always, my lovely friend".

Fellow member Louis Tomlinson also shared a separate tribute on his personal Instagram account, thanking Payne for being "the kind brother I’d longed all my life for."

Payne, who found fame on The X Factor in 2010, died after falling from the third floor of a hotel in Palermo, Buenos Aires, police say.

Police inspected the area where he fell, and found items including alcohol and a phone.

Medication was also found in his room.

In a statement, police said Payne's body was discovered when an emergency crew were called to the hotel and that "everything indicates that the musician was alone when the fall happened".

Olly Murs, who starred on The X Factor a year before One Direction, also shared his condolences on Instagram, saying he was "lost for words" and described Payne's death as "devastating".

Murs said they "always had a good laugh" when they met, mostly talking about "how annoyingly good his hair always looked, or our love for Becks, the old XF [X Factor] days and the tour we shared together.

"Liam shared the same passions as me, the same dreams, so to see his life now end so young hits hard. I'm truly gutted and devastated for his family and of course, his son Bear losing a dad."

Dermot O'Leary, who hosted The X Factor when Liam appeared, posted a photograph of the pair on stage, captioning the Instagram post: "The worst news."

"I remember him as a 14-year-old turning up to audition on The X Factor, and blowing us away singing Sinatra. He just loved to sing," he wrote.

"He was always a joy, had time for everyone, polite, grateful, and was always humble."

US singer Charlie Puth, a co-writer on Payne's 2017 song Bedroom Floor, said he was in "shock" after Payne's death.

Charlie posted images of the pair working together, alongside the caption "Liam was always so kind to me".

The Wanted star Max George described his death as "absolutely devastating news".

"Over the last few years I had the pleasure of getting to know him personally and spent some treasured time with him," he said on Instagram.

"Liam was absolutely wonderful in terms of support when Tom [Parker] fell ill, performing at the Royal Albert Hall with us for Stand Up To Cancer.

"He supported me a lot personally after Tom passed. I will never forget that.

"He was one of the first major artists I got to work with. I cannot believe he is gone... I am so upset right now, may he rest in peace."
