And back to the book, Spears will involve Britney’s mother, Lynne, 51. “Britney will call her a stage mom from hell’ and blame her for almost every ill in her life. She’ll say Lynne’s money hungry and that she was just along for the free ride. Britney thinks of her as a meddling, smothering person and blames her for her messy marriages.�?

When Britney recently told Lynne and her father, Jamie, 54, about the book, they were both devastated. “Lynne was totally crushed,�? says an insider, “and her dad warned her that if she bad-mouthed any of the family, she would regret it for the rest of her life. He knows from experience that sometimes Britney’s honesty isn’t always based in fact.�?

Meanwhile, Stevie Nicks says Britney Spears will regret her wild ways.

Nicks in her youth dealt with drug and alcohol addiction when she was with the band Fleetwood Mac and ended in rehab, reports pagesix.com.

She said: "You are sorry later, that's what I would tell them. If I had gotten it together a little more, I would have had a better career. I would have made a couple more great albums."

"I'm more worried about Spears than Lohan, because I think Lohan is a serious actress," she added.
