Carly Simon: The second verse of "You're So Vain" is about Warren Beatty

Carly Simon says the second verse of her infamous song "You're So Vain" is about Warren Beatty.

The 70-year-old singer tells People magazine that she's "confirmed that the second verse is Warren." She adds that Beatty "thinks the whole thing is about him!"

The second verse features 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."

Simon will release the memoir, "Boys in the Trees," on Nov. 24. The subjects behind "You're So Vain," released in 1972, have been a matter of speculation for years.

The singer said the No. 1 hit is about three men, including Beatty, though she isn't naming the others.

Simon was married to James Taylor, and People says she has been linked to Mick Jagger, Kris Kristofferson, Jack Nicholson and Cat Stevens.
