Lovelorn fans of “One Direction” heartthrob Niall Horan will be relieved by his latest admission to Now magazine. The 19-year-old pop star insists he’s single and open to a new relationship.

Horan’s comments come on the heels of speculation that he has started dating 20-year-old drama student Amy Green. Last week, British tabloid the Mirror reported that Horan had begun a new relationship with Green and had been spotted with her backstage at recent taping of “X Factor”, but was playing down the romance.

"Niall was introducing Amy to people as his girlfriend and they were very happy from the look of things. He was kissing and cuddling her when people weren't watching and seemed really into her,” said a source to The Mirror, who added that Horan refused to comment on his relationship with Green. "They're dating – it's early days but they're very cute together."

“She was very posh and I have to say they seemed like a great couple. It's definitely early days but Amy was on his arm as a girlfriend not just a girl friend,” added the source.

The news came after many tabloids reported that Horan was involved with “X Factor” judge Demi Lovato. Lovato herself seemed to encourage the rumors, saying of Horan, “He has a lot of great qualities. He is an amazing ­listener and makes me laugh a lot, two of the main qualities I look for.”

“He knows I have a little crush on him, and we enjoy having dinner when we get the chance,” said the 20-year-old singer. “We speak and message all the time. I don’t want a relationship over Skype; we are both in a place where we feel zero pressure to rush.”

But in a new interview with Now magazine, the singer dispelled the rumors, saying, "[I'm] definitely single.” "I'm not actually looking,” added Horan, “but if the right person came along, [I'd] definitely [want a girlfriend]."

Horan also opened up about his now famous kiss with Katy Perry at this year’s MTV Video Music Awards.

“Well, walking up those stairs the first thing I saw was her with her lips out,” he said. “I forgot about the award at that moment -- I just went straight for her lips!"

"Oh man -- she's amazing! I think she feels a little bit of ownership over me because she was the one to put me through on X Factor when she was a guest judge,” said Horan.

"I don't mind -- she isn't a bad person to be making comments on ya! Katy's super-hot. And she's really cool as well. She was the first person to say hi backstage. Our dressing room was next to hers and we were just chatting and stuff."
