Celebrities go against type to pen unexpected books.

Bill O'Reilly’s latest book “Kids Are Americans, Too” concludes even kids have rights. Really Bill? We didn’t think you thought anyone had rights. Then there's Newt Gingrich getting all touchy-feely with “A Contract With the Earth.”

If this trend continues we might be seeing these on a best seller list soon:

• Britney Spears' A Celebration of Motherhood
• Amy Winehouse's 21 Days to a Healthier You
• Mel Gibson’s Big Book of Hanukkah
