In response, the former Grey's Anatomy star said, "The kids??!! What about me??!! I thought it was a random slightly chaotic song about watermelons and sugar and... well hell I have no idea what I thought the song was about but oral sex never crossed my mind."

She added, "I guess Harry and I have different adjectives to describe the experience."

But as mentioned before, the One Direction singer has never said that "Watermelon Sugar" is a sexual innuendo. In fact, he once shared that he was inspired to write the tune after seeing the book In Watermelon Sugar by Richard Brautigan during a writing session. As he put it in a Tiny Desk interview with NPR, "I was like ‘That'll sound cool!'"

And like all art in the world, his music is up for interpretation. Harry actually encourages fans to decide what it means for themselves, previously explaining, "It's kind of why I tend not to explain songs too much because I think it's important for it to, I guess to allow it to mean whatever it means to different people."

"And I know there's songs that I've loved in my life where I find out it's about something else and I'm almost like, 'Oh, I wish I didn't know that, because it used to mean so much to me.' And it's amazing if people can relate to your music." He continued, "I just love music and I make what excites me and I think if somebody else can relate to it and take something from it, then that's kind of the biggest compliment they can give me."

Katherine's revelation comes hours after "Watermelon Sugar" received a Grammy nomination for Best Pop Solo Performance. Additionally, his album, Fine Line, was nominated for Best Pop Vocal Album, while "Adore You" got a Best Music Video nod. 

This is the artist's first time being nominated for a Grammy as a solo artist. To see who else is a first time nominee, check out our story here!
