Recently though, the 17-year-old opened up about one of the few dates she has been on and, needless to say, it didn't go well.
Eilish told all on Tuesday's the Howard Stern Show where she revealed details about the scarring experience, which happened when she was 13.
Long story short, the guy chanced his luck at a kiss. But, like the self-conscious teen boy he was, he had to give his unsolicited two cents right after.
"[He] said, 'That was not as magical as I thought it was gonna be,'" she said.
But the fun didn't stop there.
As Eilish recalled, "he was super rich and his butler — literally, his butler — his butler was there the entire time, but in a different movie theatre."
Finally, the young man decided to ditch his date when the going got tough – asking his butler to take him home.
"I was stuck there. No one told me they were, like, gonna leave," she continued, before adding that a baby came up to her at that moment.
"I was like, 'Oh my god a baby and it's smiling at me.' And I smiled and it started screaming and crying and ran away," Eilish said. "And then I went home and cried. And then the next day it was Valentine's Day. That was one date I had."
But, don't call Eilish bitter. "Dude is hella ugly now."
