Simon Schuster has signed Britney Spears to a multimillion-dollar book deal. The huge money deal was put together over the last few months, according to Deadline's sources close to the case.

According to Page Six of the New York Post, the arrangement is for $15 million and will cover both her professional and personal lives. The deal was initially reported by Page Six.

The agreement comes just over four months after a Los Angeles Superior Court judge formally removed Spears' conservatorship, which had been in place for nearly 14 years.

According to sources, the book contract has nothing to do with Jamie Lynn Spears' memoir, Things I Should Have Said, which was published last month.

In a since-deleted Instagram post, Britney Spears had lashed out at her sister’s book, writing, “Congrats best seller…..The nerve of you to sell a book now and talk s—t but your f—king lying…..I wish you would take a lie detector test so all these masses of people see you’re lying through your teeth about me !!!! I wish the almighty, Lord would could come down and show this whole world that you’re lying and making money off of me !!!! You are scum, Jamie Lynn.”

A subsequent cease and desist salvo from Britney Spears’ lawyer Matthew Rosengart read, “Although Britney has not read and does not intend to read your book, she and millions of her fans were shocked to see how you have exploited her for monetary gain. She will not tolerate it, nor should she.”
