Harry Styles says he was shocked to learn many of the early fans of his hit song, "Watermelon Sugar," were little kids.

Styles told Rolling Stone that the mega-hit-turned-single, first featured on his 2019 album "Fine Line," seemed to be connecting with a youthful crowd early on.

"Sometimes you'll meet people, and they'll be like, 'Oh, can you meet my child? They're a massive fan,' and the child's like 18 months old. This person's a massive fan?" Styles told Rolling Stone.

"And I remember," Styles continued, "someone coming up to me at a party with their son, who was really small, and he started singing 'Watermelon Sugar,' and I was like, 'Oh, okay.'"

Then came the videos.

Styles said more than ever before, friends were sending videos of their kids singing and dancing along to the tune.

"It wasn't a single when we put [it] out," he said. "It was just like, 'Okay, interesting … This is a high volume of videos of small children singing the song.'"

Styles has previously spoken about the true meaning of the song, which, he says, is about the "sweetness of life" but also the "female orgasm."

Speaking to Rolling Stone, Styles added that it blew up in a way that he wasn't expecting during the COVID-19 pandemic in 2020.

"We couldn't do anything, and it kind of just did its thing. I think it was a really nice reminder that songs have the power," he said.

"It's timing," Styles continued, "and if people connect with it, and how people are feeling, and what they feel like they want … that part of it feels like it's just really lucky."
