Zayn Malik also shared a heartbreaking tribute, writing, "I lost a brother when you left us and can’t explain to you what I’d give to just give you a hug one last time and say goodbye to you properly and tell you that I loved and respected you dearly."

"I will cherish all the memories I have with you in my heart forever, there is no words that justify or explain how I feel right now other than beyond devastated," he continued.

On his Instagram account, Louis Tomlinson, 32, also shared a touching tribute to his "brother" Payne.

"I am beyond devastated to be writing this but yesterday I lost a brother. Liam was somebody I looked up to everyday, such a positive, funny, and kind soul," he wrote. "I first met Liam when he was 16 and I was 18, I was instantly amazed by his voice but more importantly as time went on I got a chance to see the kind brother I'd longed all my life for."

The One Direction singer died from "polytrauma" and "internal and external hemorrhage," according to a press release from the National Criminal and Correctional Prosecutor's Office No. 16  in Argentina. Authorities are investigating the circumstances surrounding his death, they said in the release translated from Spanish to English, but prosecutors believe Payne was alone when the fall occurred.

One Direction band took an indefinite hiatus in 2016 following the release of their fifth album, "Made in the A.M." All members, including Malik, who left the group in March 2015, went on to pursue solo careers.

"It is definitely really sad for us. But obviously, we're going back into it. So it's not goodbye; it's just, 'See you later,'" Payne told USA TODAY in 2015 about their hiatus. "It's like what Tigger used to say: 'Ta-ta for now.'"
