The more you know.

Imagine it: just some quality family time listening to Harry Styles (who just got nominated for his first Grammy Award as a solo artist). "Watermelon Sugar" comes on. Life is good. Kids are dancing. That's exactly what Katherine Heigl thought she was enjoying, but when a fan let her know what Styles's tune was actually about, she admitted that she didn't know.

Instagram's @CommentsByCelebs captured the exchange, which just goes to show that Styles's lyrics are just that good.

"This song is about going down on women but the kids don't need to know that," a fan commented on Heigl's clip.

Heigl responded, "The kids??!! What about me??!! ... I have no idea what I thought the song was about but oral sex never once crossed my mind ... I guess Harry and I have different adjectives to describe the experience."

Styles's "Watermelon Sugar" lyrics use metaphors about the taste of different fruits to describe a specific kind of encounter. Slant Magazine's music critic, Anna Richmond, explained one interpretation of the song, saying that Styles "describes a sexual encounter in terms of sweet fruits and summer nights, building to an ecstatic, horn-filled climax."

Styles hasn't explicitly confirmed the meaning behind the tune, but fans and critics alike have guessed that it's very much about oral sex.

"Watermelon Sugar, which at this point is out, and everyone's kind of figured out what it's about," Zane Lowe said on his Beats 1 show. "The joys of mutually appreciated oral pleasure."

Styles, being Harry Styles, said simply, "Is that what it's about? I don't know."

"That's what everyone's saying. Always good to leave it open to interpretation," Lowe added.

Styles's response? "Oh, yeah. Of course."
