The One Direction star and his bandmates Harry Styles, Zayn Malik, Louis Tomlinson and Niall Horan has become close to the 'Boyfriend' hitmaker in recent years, but doesn't think he has as much fun as the British group because he doesn't get to perform with anyone else.
He said: "Not in a patronising way, but I kind of feel sorry for him. I know he's got friends around him and they go on tour with him. But they're not going through the same situation as these boys are with me.
"If something bad happened to me tomorrow, Louis would be there for me 100 per cent. People sometimes ask if I want to be a solo artist, but it just wouldn't be any fun being on your own."
Despite touring the world now and rarely being at home, Liam does like to have some time away from the band - even if it's still with one or two of his bandmates.
He told Now magazine: "It's important to have a life outside the band. But at the same time I spent the night yesterday at Zayn's house. We all have this amazing brotherhood and that's what makes this job so special. If we didn't have each other, I think we'd crumble a little bit."
