Paula Deen cookbooks, including Amazon No. 1 bestseller, cancelled by publisher

Paula Deen's publisher has cancelled a multibook deal with her, including an upcoming cookbook that's the No. 1 seller on

Ballantine Books announced Friday it had cancelled publication of "Paula Deen's New Testament: 250 Favorite Recipes, All Lightened Up." The book was scheduled for October.

Deen's agent, Janis Donnaud, tells The Associated Press four other planned books under contract also are cancelled.

Deen has lost many of her business relationships following revelations she used a racial slur in the past. Sears Holdings Corp and J.C. Penney Co. say they're cutting ties with Deen, following similar announcements from Wal-Mart Stores Inc., Target Corp. and Home Depot.

Last week, the Food Network said it wouldn't renew her contract.

Deen specializes in Southern comfort food. She says she's not a racist.
