Britney Spears' eagerly awaited tell-all book may not disclose everything she intends to reveal, leading some to question if the pop star will abandon the project as lawyers begin to take control, according to RadarOnline.com.

Britney reportedly signed a $15 million book deal with Simon & Schuster, with her memoir set to be released by the end of the year. However, lawyers are said to be halting the creative process for the singer of Oops!... I Did It Again, as her father, Jamie Spears, gears up "to take action if there be anything that merits untruths or libel" relating to his daughter's abuse allegations.

Associates of Jamie claim that he won't "simply let his daughter write what she wants about him and destroy his reputation."

A friend of Britney's father informed The Sun that "the legal team at the publisher knows Jamie is unhappy about what is coming and has charged his lawyers to take steps to prevent untruths being told," continuing, "It is down to the publisher's lawyers to decide what they will print and to leave out."

The Las Vegas-based source stated, "Britney will not get to print and say what she wants," cautioning, "He is not simply going to take this all because his daughter said it. He is willing to fight to present his truth even if that means filing lawsuits."

Jamie is reportedly determined to prevent his daughter from disseminating claims about her 13-year conservatorship, with his friends arguing that Britney's book extends beyond the realm of free speech.

The insider mentioned that "naturally, his legal team knew that this would be a very complicated case given the US' free speech legislation," but Jamie believes he has the right to question Britney's state of mind during the conservatorship.

The source added, "Across Europe, there are very different libel rules. And that would need to be taken into consideration."

RadarOnline.com has contacted Britney and Simon & Schuster for comments.

Sources depict Britney's manuscript as "a story of triumph," detailing her most vulnerable moments, including her childhood, her breakup with Justin Timberlake, shaving her head, and her struggle with her family over her conservatorship.

The book is also described as "a story of survival, finding her way out of the crippling conservatorship to finding happiness with her husband, Sam Ashgari."

The Grammy-winning artist's memoir is scheduled for release in the fall, provided legal teams do not intervene.
