Carly Simon has finally put an end to a 38-year-old mystery about the subject of her 1972 hit You’re So Vain.

The renowned songwriter, who refused to reveal the inspiration behind the track, sparked years of speculation about her song aimed at a former lover.

Guesses to the one of the greatest mysteries in music included the names of Warren Beatty, Sir Mick Jagger, and James Taylor, The Herald Sun reported.

And now, the 64-year-old star has let slip the first name of the man in a new recording of the song, in which the name “David” is whispered, backwards.

Simon told Uncut magazine: “I’m just going to tell you this. The answer is on the new version of You’re So Vain. There’s a little whisper — and it’s the answer to the puzzle.”
