The pop star has been linked to 20-year-old Amy Green after they reportedly attended filming of U.K. Tv show The X Factor together earlier this month (Oct12).
A source tells British newspaper Sunday Mirror, "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... It's definitely early days but Amy was on his arm as a girlfriend not just a girl friend."
Horan was previously linked to U.S. pop star Demi Lovato, but he insisted the singer is just a friend.
