The One Direction singer has been linked to the 'x factor' judge after they both spoke of their admiration for each other, but he insists there's nothing going on, even though he would like there to be.
When asked if he was romancing Demi, Niall exclusively told BANG Showbiz: ''I wish! No there's nothing going on, but she's a lovely girl.''
Niall - who was speaking in the Virgin Media Louder Lounge at Virgin Media's V Festival over the weekend - was first linked to Demi earlier this year after they both revealed they had crushes on each other.
Demi said: ''I would snog Niall. I do have a little crush on him.''
''I love Niall, he is so cute. I hear he's really sweet and he's a cutey pie!''
Meanwhile, when asked who his celebrity crush was, Niall, 18, replied: ''Demi Lovato - she's a beautiful girl.''
He was then asked who he prefers out of Kim Kardashian or Demi and he said: ''Demi definitely.''
Demi, 20, has also said how she was ''thankful'' to have Niall in her life but insisted they weren't dating.
She said: ''We've actually become really close friends and you know I'm really thankful I have someone who supports me in all aspects. You know, if I need somebody to talk to he's there for me. But no, we're not dating.''
