Carly Simon just told us who “You’re So Vain” is about, solving one of music’s great mysteries

You’re so vain / you probably think this song is about you has always been one of the catchiest and also most mysterious lines in music. Oh, Carly Simon, whoever did you mean? (And let’s be real here: This was some next-level shade, because the person it’s actually about can’t even wonder if it’s about them for fear of being vain. Well played, Carly, well played.)

But finally, the mystery has been solved. Well, kind of. In a recent interview with PEOPLE about her memoir, Boys in Trees, the 70-year-old singer revealed that the second verse is about actor Warren Beatty, whom she was in a relationship with years ago. But only the second verse, she clarified: “I have confirmed that the second verse is Warren.”

And yes, Warren does know about his role in the famous song. In fact, it turns out Carly’s claims about his vanity are right, because according to her, “Warren thinks the whole thing is about him!” Quite vain indeed. Here’s the second verse, ICYWW:

Yep, it’s stuck in our heads again, too.

So who were the other verses about? Two other men, Carly said, but she hasn’t said a peep. Nor will she, “at least until they know it’s about them,” she told PEOPLE. They’ve gotta prove their vanity first. Either that, or Carly could just outright tell them. But will she?

“Probably, if we were sitting over at dinner and I said: ‘remember that time you walked into the party and … ” she told PEOPLE . “I don’t know if I’ll do it. I never thought I would admit that it was more than one person!”

Obviously, we’re all dying to know who it is, which has totally thrown Carly for a loop. After all, it was released over two decades ago, and we’re all still wondering who, exactly, is so vain. “Why do they want to know?” Carly told PEOPLE. “It’s so crazy!”

Either way, PART OF THE MYSTERY HAS BEEN SOLVED, guys. We can all rest partially easy. (Except for Warren Beatty.) Now that “You’re So Vain” has officially got stuck in your head, time to listen to it on repeat.
