One Direction singer Niall Horan has revealed what his ideal girlfriend would be like.

The Irishman is one of three members of the pop group who are currently single, with Louis Tolimson and Zayn Malik - who is dating Little Mix's Perrie Edwards - both having girlfriends.

Speaking on the Ellen DeGeneres show, Horan opened up on what he is looking for in a girl, saying:

"I like someone that's cute. Someone I can have a laugh with. And I also like people that are American. And you all qualify."

Longstanding rumoured love interest Demi Lovato meanwhile fits the bill for Horan, but both the 'One Thing' man and the X Factor USA judge have denied that there is any romance.

As previously reported, One Direction have tapped up Super Size Me director Morgan Spurlock to work on their first ever 3D film.
