Lynn Spears Book No Bombshell

Sept. 17, 2008— -- Perhaps the pictures tell the story.

The day before Lynn Spears' memoir "Through the Storm" about her famous daughters Britney and Jamie Lynn Spears was to be released, the Spears women, along with Jamie Lynn's 3-month-old baby Maddie, were photographed sitting on the curb outside Britney's Los Angeles home looking relaxed and affectionate with smiles on their faces.

The occasion was the birthday bash for Britney's sons, Sean Preston, who turned 3 on Sunday, and Jayden James, who had celebrated his second birthday two days earlier.

If the daughters were upset about the family secrets Spears spills in her tell-all -- including Britney losing her virginity at 14 and doing cocaine shortly after -- they sure didn't show it. It appears Spears' book isn't causing the family storm many predicted.

Graciella Sanchez, Jamie Lynn's agent, declined to comment for the story. Calls to Britney's rep and Lynn's publicist were not returned.

Last week, The New York Post reported that Britney was furious with her mother for detailing her past, but her rep told the paper, "This is false."

Celebrity blogs were reporting that Britney and her brother, Bryan, had yet to read the book, but Jamie Lynn was thrilled with what she had read.

Spears was quoted as saying: "Jamie Lynn loved the book. I started to cry because I told her, 'I wanted so much for you to like it.' And she got up and kissed me on the cheek and said, 'Mama, thank you so much.'"

Spears also reportedly said that writing the book helped her mend her relationship with Britney.

Albert Lee, a senior editor from US Weekly, told ABCNews.com that originally Britney worked on the book with her mother.

"Lynn Spears never intended it as a tell-all," Lee said. "It was actually, believe it or not, an advice book, saying 'I've raised two famous successful daughters.' She was never going to tell you all the sordid details. Britney and her mother even collaborated on the book together. But that was way before she shaved her head and had a shocking freefall."
