One Direction fans in Argentina sang the boyband's song Infinity to pay homage to member Liam Payne on Wednesday night, who died in Buenos Aires after falling from his third-room balcony according to Argentine police.
Fans also lit candles and clapped for the 31-year-old performer before holding a minute of silence.
The moment touched the heart of 25-year-old Yamila Zacarias, who told Reuters she was unable to see One Direction play live when she was younger because the tickets were too expensive.
"This was the only time I was able to clap for him," she said as she fought back tears.
Buenos Aires police said Payne fell from the third floor of the Casa Sur Hotel in the Palermo neighbourhood of Argentina's capital before medics confirmed his death, in a statement to the Associated Press (AP).
Police responded to an emergency call from the hotel manager who had become concerned for the welfare of a guest, the AP said.
