-- 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."
