There's said to be fierce rivalry in the One Direction camp, as the American girls go crazy for Niall Horan.

As the boys tour the U.S., the 19-year-old is apparently being mobbed by fans, while Harry Styles, who is arguably the biggest star back here, is left in the wings.

And Zayn Malik is apparently not far behind.

Niall Horan is said to be greeting the most attention stateside, which has given Harry Styles a knock to his ego, with him supposedly the most popular member in the UK

'All the boys are popular, but the
girls in the U.S. seem to be absolutely obsessed with Niall,' a source told Closer magazine.

'They love
the fact he's Irish and looks like the perfect all-American boy. He gets
swamped with girls wherever he goes.

'Zayn is a close second – he's very
cheeky and confident, which is going down well. It's definitely been a
bit of a knock to Harry's ego, as he's used to being the heartthrob back
home. It's only natural that the boys are now competing for attention.
It's causing a bit of tension.'

A friend added that the band were trying not to 'get on each others' nerves ahead of their three-month U.S. tour which starts in May.

They will play at 20 venues.

'The boys are feeling a bit cooped-up,
as they're spending 24/7 together, and are starting to get a little
homesick,' the friend said.

'They don't want silly rows to affect them, so are trying to
keep fighting to a minimum.'

The boys were pictured arriving at Toronto Pearson airport over the weekend, and yesterday at Montreal airport.
