The “Slow Hands” singer went on to reminisce about his time singing alongside Liam in One Direction.

“All the laughter we’ve had over the years, sometimes over the simplest things, always comes back to me despite the sadness,” Niall added. “We were able to achieve our wildest dreams together and I will forever cherish every moment we had. The bond and friendship we had doesn’t happen often in life.”

Niall, who had Liam and his girlfriend Kate Cassidy As a guest at his last concert in Buenos Aires, he also talked about what it was like to see his friend for the last time.

“I feel so lucky to have been able to see him recently,” Niall wrote. “Unfortunately, I didn’t know that after saying goodbye and hugging that evening, I would be saying goodbye forever.
