Carly Simon Spills a Big 'You're So Vain' Secret

— -- In "You're So Vain," Carly Simon sings, "You're so vain, you probably think this song is about you."

Now, she's revealing who she's referring to -- at least in one part.

"I have confirmed that the second verse is Warren [Beatty]," Simon told People magazine. "Warren thinks the whole thing is about him!"

Simon, 70, released "You're So Vain" in 1972, around the time she married her now ex-husband James Taylor. The song's second verse contains the lyrics, "You had me several years ago when I was still quite naive/Well you said that we made such a pretty pair, and that you would never leave./But you gave away the things you loved and one of them was me/I had some dreams, they were clouds in my coffee."

The other lyrics in the song, she said, refer to two other men, though she doesn't plan to reveal their identities anytime soon.

"At least [not] until they know it's about them," she said.

"I never thought I would admit that it was more than one person!" she added. "Why do [people] want to know? ... It's so crazy!"
