|Ali McGinley & Niall Horan|
She said: "He genuinely may be one of the nicest men I've ever met. We're close."
Quizzed on twitter about whether she and Niall are dating, Ali would only say the pair are "happy campers".
She wrote: "I can confirm that we're both happy campers, nothing less nothing more x".
Although they hail from the same town, Ali and Niall, 18, only met quite recently, but hit it off straight away, though they are concerned about the impact the 'What Makes You Beautiful' hitmaker's schedule would have on a relationship.
A source told The Irish Sun newspaper: "Ali and Niall are from the same town but didn't really know one another until a few months ago.
"Ali attends school in Alexandra College in Dublin and wouldn't have known Niall from when they were younger.
"He thinks she is gorgeous and she is pretty sweet on him too but Niall's schedule means it would be pretty hard to have a relationship with anyone."
