Niall Horan is ''scared'' of big crowds.
The One Direction hunk, who is currently in the midst of the group's European 'Take Me Home' tour, has admitted he often feels ''claustrophobic'' while mobbed by adoring fans, but knows he is in safe hands when surrounded by his security guards.
He told We Love Pop magazine: ''I'm quite claustrophobic and I don't like everyone crowding around and shouting the same questions. I get a little bit scared sometimes. It's all good as we've got a good security team.''
Niall, 19, also spoke about how he and his bandmates - Harry Styles, Louis Tomlinson, Zayn Malik and Liam Payne - are closer than ever and only ever argue about minor things, such as what radio station to have on during their time on the tour bus.
He added: ''We've got to the stage now where we know each other's boundaries. If there's an argument it's over what's on the radio, or, 'Turn up the window, it's freezing.' ''
The Irish star is rumoured to be dating model Zoe Whelan and the pair have become so close, Niall invited the brunette beauty to his brother's wedding in his hometown of Mullingar, County Westmeath.
An insider said: ''Niall has been secretly seeing Zoe for a couple of months after he met her backstage.
''She's a Dubliner but is based in London to work on her modelling career. Zoe's travelled all over the UK to meet up with Niall on the band's tour.
''But the biggest sign he's really serious about her is that he introduced her to his whole family at his brother's wedding.''
