James Corden has lavished praise on One Direction's Harry Styles.

The TV host is good friends with the 'Kiss You' crew and he helped create the band's recent 'Best Song Ever' video.

Speaking to the Observer, Corden said that he hopes enough "normal" people are surrounding the "adorable" Styles to keep him grounded. He said:

"He's an adorable guy and I can't begin to imagine what his life is like right now and how it's changed in the past three years. And, I feel like the more normal people he has around, probably the better."

Corden also revealed that he became friends with Styles and bandmate Louis Tomlinson whilst they were on the X Factor in 2010. He said:

"So, Louis Tomlinson who is a member of One Direction, his mum was a chaperone on [TV drama] Fat Friends. So Louis used to come to the set with his mum and since I was the only sort of young person around we would kick a football around, things like that. Then when he got into The X Factor', he got in touch and said, 'I'm in London and I don't know anybody'. So he brought Harry round and we played Fifa and had a pizza, so that's how [we became friends]."
