Grammy Award-winning artist Harry Styles posted an emotional tribute to Liam Payne, his One Direction bandmate who died after falling from his hotel balcony in Buenos Aires, saying the time they spent together will forever remain among the most cherished years of my life.

In a post with a photo of Payne singing onstage, Styles shared Thursday on Instagram that he was devastated by his friends death the day before.

His greatest joy was making other people happy, and it was an honour to be alongside him as he did it, wrote Styles, who rose to stardom alongside Payne when their boy band launched on British TV series The X Factor in 2010. They were both teenagers at the time.
