NEW YORK (AP) — 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!"

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.
