Harry Styles has dismissed speculation his new song 'Daylight' is about Taylor Swift.
The 'As It Was' hitmaker laughed off the suggestion he'd penned a track about his former girlfriend - who he dated for several months in late 2012 to early 2013 - for his new album 'Harry's House' because it shares a title with one of the 'Love Story' singer's own songs.
Although Harry confirmed the song was about a woman who hadn't responded the way he'd hoped, he dismissed DJ Howard Stern's theory that it was about Taylor.
Howard noted: "You're smiling".
But his SiriusXM guest replied: “You know I’d love to tell you you’re spot-on, but you’re not. We will always wonder.”
And the former One Direction star played coy when asked if another track on the record, 'Cinema', is about his current partner, actress-and-director Olivia Wilde.
He said: “Most of the time when I write songs they kind of start out as, like, I guess mine.
“It’s important to write from whatever you’re going through at the time."
The 28-year-old star no longer goes out partying because he feels he owes it to his fans to be in the best shape possible for his concerts.
He said: “I try and think of it like almost like an athlete would approach something like that… it’s a pretty incredible thing I get to do and I love it so much so to treat it as such it doesn’t feel like a sacrifice.
"For this two hours a night I want to give it 100%.”
Harry admitted he found it "incredibly shocking" when Will Smith slapped Chris Rock over a joke about his wife, Jada Pinkett Smith, at this year's Oscars and admitted the incident made him "very uncomfortable".
But he added: “I think there’s a boundary that people cross because it’s a blurry line about what part of you is available to people and what is not.
“Sometimes they take parts of you that don’t belong to them.”
