Standing out: One Direction's US management are trying to make Harry Styles the lead singer, saying American band's who have a frontman make it bigger
They were put together as equals on the 2010 series of X Factor.
But One Direction's U.S. management are trying to make Harry Styles into the lead singer, with sources saying boybands in America that have a recognised frontman tend to make it bigger than those that don't.
The teenager, who turn 18 today, has been given leading roles during their current tour stateside.

Ready for the big push stateside: One Direction with Nickelodeon's iCarly star Miranda Cosgrove
The ex-boyfriend of The Xtra Factor host Caroline Flack was yesterday continuing the publicity rounds with his band mates- Louis Tomlinson, 20, Zayn Malik, 19, Niall Horan, 18, and Liam Payne, 18.
The group were seen in a number of funny poses during the photoshoot at a studio in Los Angeles.
Harry led the band when they filmed a guest spot on Nickelodeon show iCarly, with Carly, played by Miranda Cosgrove, 18, developing a crush on him.

But the group group want to stick together.
A friend told the newspaper: 'They are determined to carry on the way they have been – without a lead singer. Harry certainly hasn’t asked for all this attention.'
Harry has already caught the eye of the offspring of Hollywood royalty, Katherine Schwarzenegger, daughter of action man Arnold.
After tweeting last week that she thought he was cute after watching one of the band's videos, she managed to blag her way onto the iCarly set.
But Harry is wary of her tough-taking, former governor father.
