Harry Styles is currently in America with One Direction

US record executives are reportedly trying to encourage Harry Styles take the lead in One Direction.

The boys are currently in America filming a cameo for hit Nickelodeon show iCarly before they head on tour with Big Time Rush - and Columbia music are sure they'll be a hit if the spotlight's put on Harry.

'They decided long ago that Harry is a natural front man,' says an insider.

'He's funny, confident and has a great voice.'

But Harry, 18, and his band mates Louis Tomlinson, 20, Zayn Malik, 19, plus Liam Payne and Niall Horan, both 18, don't want to change their set-up.

'They are determined to carry on the way they have been - without a lead singer,' a friend tells Daily Star.

'Harry certainly hasn't asked for all this attention.'
