Singer Carly Simon says that British media made a mistake last week when they said music mogul David Geffen was the subject of her 1972 song “You’re So Vain.”

The identity of the man addressed in the hit song is one of pop music’s enduring secrets, with the subject often thought to be Simon ex-boyfriends like Mick Jagger, Kris Kristofferson, Cat Stevens, or Warren Beatty, or her onetime husband James Taylor.

Last week, according to the Daily Mail, Simon revealed the subject of the song to be David Geffen, the gay billionaire who was then the head of her Elektra record label. Simon reportedly says his name backwards in a new recording of the song.

However, according to Roger Friedman at Showbiz411.com, Simon e-mailed him Saturday to deny the reports as “mistaken.”

“What a riot! Nothing to do with David Geffen! What a funny mistake! Someone got a clue mistaken for another mistake!” wrote Simon, according to Friedman.

Simon apparently did not know Geffen in 1971 when she wrote the song.

The identity of the song subject remains a mystery.
