Beliebers and Directioners praised Justin for acknowledging their sadness over Liam's passing.

"Justin reposted 😭 thank you for validating my grief over Liam and please take care of yourself Justin, i love you," one fan commented.

Another Instagram user commented: "Beliebers are joining Directioners in their grief."

Scores of people, including Liam's former One Direction group members, have paid tribute to Liam over the past few days.

"I am truly devasted by Liam's passing," Harry Styles wrote in a statement. "My heart breaks for Karen, Geoff, Nicola and Ruth, his son Bear, and all those around the world who knew and loved him, as I did," he added.

Cheryl Cole, the mother of Liam's seven-year-old son, described his passing as an "earth-shattering event".

"Liam was not only a pop star and celebrity, he was a son, a brother, an uncle, a dear friend and a father to our 7-year-old son. A son that now has to face the reality of never seeing his father again," she wrote.

The British singer also slammed the abhorrent reports that have been shared in the wake of his death.

"What is troubling my spirit the most is that one day Bear will have access to the abhorrent reports and media exploitation we have seen in the past two days. It is breaking my heart further that I cannot protect him from that in his future. I am begging you to consider what use some of these reports are serving, other than to cause further harm to everyone left behind picking up the pieces."
