Niall Horan
Niall Horan had been touring in South America and he met-up with Liam at his concert in Buenos Aires just two weeks before he passed.
He appeared stony-faced as he arrived at the funeral hand-in-hand with his girlfriend Amelia Woolley.
After Payne died, Niall said: "I feel so fortunate that I got to see him recently. I sadly didn't know that after saying goodbye and hugging him that evening, I would be saying goodbye forever. It's heart-breaking."
