Demi Lovato addresses Niall Horan romance rumours
The X Factor judge was linked to Niall earlier this year after the pair both admitted they had the hots for each other - but Demi insists they're just good mates.
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."
It was recently revealed that Niall, 18, and 19-year-old Demi had been Skyping each other, fuelling reports they were in a long-distance relationship.
But Demi has insisted that she's too busy with her career to have time for a boyfriend.
She added to MuchMusic: "I'm single. It wouldn't be fair to anybody if I was dating them because I wouldn't be able to give them my attention. And I've never really stayed single for longer than a couple of months.
"So, I'm experimenting with this and I'm really trying to get to know myself and do what's best for me as a person and as a woman."
Nonetheless, Niall has happily revealed Demi is his celebrity crush and that he thinks she's a "beautiful girl".
And the feeling's definitely mutual.
Demi has previously 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!"
