Britney’s mum to write book about parenting.

As lawyers for Britney Spears and her ex-husband fought a court battle over custody of their two young sons, a publisher said on Friday that the pop star’s mother is writing a book about parenting.

Religious publisher Thomas Nelson said it will publish “Pop Culture Mom: A Real Story of Fame and Family in a Tabloid World,” by Lynne Spears. Nelson spokesman Curt Harding said the book, to be out next spring, will be about Lynne Spears’ raising three children and will have a religious element.
