Hillary gets a helping hand from Bill

HILLARY CLINTON was so mobbed at her New York book party that it seemed she’d never get around to signing all the books. Luckily, husband Bill was helping.

The former president, who until now has let his wife enjoy the spotlight as her memoir, Living History, sells like hot cakes, smiled and signed away his own autograph on the volume apparently in as much demand as hers.

Publisher Simon & Schuster, which threw the Manhattan bash on Monday, declared Living History to be the top-selling adult nonfiction book ever, based on first-week sales of 600,000 copies. An additional 500,000 copies have been ordered on top of an extraordinary initial printing of one million copies, the publisher said.
