Demi Lovato is "thankful" to have Niall Horan in her life

She said: Weve actually become really close friends and you know Im really thankful I have someone who supports me in all aspects. You know, if I need somebody to talk to hes there for me. But no, were not dating."

However, Niall shouldn't be upset that he and Demi are not dating as the 19-year-old beauty insists she is only single because she is so busy with her career.

She added to MuchMusic: Im single. It wouldnt be fair to anybody if I was dating them because I wouldnt be able to give them my attention. And Ive never really stayed single for longer than a couple of months. So, Im experimenting with this and Im really trying to get to know myself and do whats best for me as a person and as a woman."

Niall 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."
