Paris Hilton, Charlie Puth and More Mourn Liam Payne's Death

One Direction member Liam Payne is receiving tributes from Hollywood and beyond after his unexpectedly death at the age of 31 on Wednesday.

The UK-born pop star was staying at the CasaSur Palermo Hotel in Buenos Aires, Argentina, when he fell from the third floor, state police said.

Heiress Paris Hilton spoke out about the devastating news on X, writing, “So upsetting to hear the news of @LiamPayne passing. Sending love and condolences to his family & loved ones. RIP my friend.”

Singer Charlie Puth took to his Instagram Story to share a slew of photographs with Payne and a grieving message.

“I am in shock right now,” he wrote. “Liam was always so kind to me. He was one of the first major artists I got to work with. I can not believe he is gone … I am so upset right now, may he rest in peace,".

Fellow musician Zedd added, “RIP Liam… I can’t believe this is real… absolutely heartbreaking …”.

Wesley Stromberg, a member of the boy band Emblem3, said he was “heartbroken.”

“I cannot believe the news about @LiamPayne … such a cool talented dude,” he wrote on X. "Absolutely heartbreaking. Rest in Paradise,".

“R.I.P. Liam Payne wow I can’t believe it prayers up for the family,” rapper Juicy J. added.

English singer Mabel penned on her Instagram Story, "FOR SO MANY YEARS I ALWAYS KNEW I COULD CALL YOU FOR SUPPORT AND BIG BROTHERLY ADVICE BUT NOW YOU'RE GONE... MY THOUGHTS AND PRAYERS ARE WITH LIAMS FAMILY AND FRIENDS DURING THIS TIME YOU'LL BE SO MISSED,".

Several witnesses told TMZ they saw the singer fall after he was behaving erratically around 5 p.m. local time.

The outlet reported that the “Night Changes” singer smashed his laptop and was carried back to his hotel room.

It’s unclear if the fall was an accident or intentional. Authorities are investigating the circumstances of his death.

Photos obtained by TMZ showed the singer's body on the hotel’s deck while surrounded by chairs and tables.

The photo didn’t show the “Night Changes” crooner’s full body but his tattoos were visible on his arm and hip.

Born in Wolverhampton, England, Payne rose to fame alongside his One Direction bandmates, Harry Styles, Niall Horan, Zayn Malik, and Louis Tomlinson in 2010.

He stayed in contact with the boy group since they split in 2015.

Earlier this month, Payne most recently attended Horan’s concert at the Movistar Arena in Buenos Aires.

The British icon previously opened up about hitting “rock bottom” and turning to drugs and alcohol while performing with One Direction.

"I've suffered a bit of a dark time in my life," Payne shared in a 2023 interview with On Demand Entertainment, "and honestly, I wouldn't be here without the boys."

Payne shared 7-year-old son, Bear Grey with ex-girlfriend Cheryl Cole, whom he dated from 2016 to 2018.
