Niall Horan is reportedly dating drama student Amy Green.The One Direction singer - who has been linked to Demi Lovato in the past - reportedly took the 20-year-old beauty with him when he visited the set of 'The X Factor' last weekend and introduced her as his girlfriend. A source told the Sunday Mirror newspaper: ''Niall was introducing Amy to people as his girlfriend and they were very happy from the look of things. He was kissing and cuddling her when people weren't watching and seemed really into her. ''She was very posh and I have to say they seemed like a real couple. It's definitely early days but Amy was on his arm as his girlfriend and not just a girl friend.'' Sources close to Niall say the pair have only recently started dating but he is very happy with Amy. A friend explained: ''They're dating - it's early days but they're very cute together.'' Niall recently revealed his ideal first date would be a visit to a theme park. He explained: ''He said: ''I can be quite cheesy. My ideal first date would be to do something fun and a bit crazy, like go to a theme park. ''I'd give her lots of cuddles. I wouldn't want to go somewhere to eat - that would be way too awkward.''
