Harry Styles has confirmed the upcoming song "Daylight" is not about his ex-girlfriend Taylor Swift. 

When Styles appeared on Howard Stern's SiriusXM show Wednesday, the host explained to him why fans think the song, which is from his upcoming music album "Harry's House," is about Swift.

The 68-year-old host read out the track's lyrics: "Reading your horoscope, you were doing cocaine in my kitchen/ You never listen/ I hope you're missing me by now/ If I was a bluebird I would fly to you/ You be the spoon, dip you in honey so I can stick to you."

Styles admitted that the music track was about a woman who didn't love him back the way he anticipated, which made him feel frustrated.

Stern reminded him that Swift had also dropped a music track titled "Daylight." It was from her 2019 music album "Lover." The host then remarked, "You're smiling."

"You know I'd love to tell you you're spot-on, but you're not," Styles replied.

Stern then read a line from another song, titled "Cinema" from the same album: "If you're getting yourself wet for me, I guess you're all mine," and asked Styles how did he present a song like this to his current girlfriend Olivia Wilde.

"When I write songs, they kind of start out just, I guess, mine," the singer replied. "I think it's important to write from what you're going through at the time and trying to turn life into what you make. I guess it's like, the most you can kind of capture a moment is kind of being true to that."

"I had a wonderful experience being directed by Olivia. I think there is something that obviously…acting is kind of very uncomfortable at times. I think you have to trust a lot," he added.

"Harry's House" will release this Friday, while a movie helmed by Wilde, titled "Don't Worry Darling," will drop on Sept. 23.
