Liam Payne and Louis Tomlinson were connected for life through their stint in One Direction, which became one of the most successful boy bands of all time. But their friendship wasn't always smooth-sailing,

Dermot O’Leary, who hosted The X Factor while Payne was a contestant, shared an image of him and Payne on Instagram, with the caption: “The worst news. I remember him as a 14 year old turning up to audition on The X Factor, and blowing us away singing Sinatra. He just loved to sing.”
