According to the BBC, the letter expressed Spears’ belief that her sister has “exploited her for monetary gain”, adding that she, “Will not tolerate it, nor should she.”
While it appears that Spears does not take direct issue with the book, entitled Things I Should Have Said, she reportedly objects to her sister “referencing [her] derogatorily” while promoting it.
The letter, from Spears‘ lawyer Mathew Rosengart, states: “Publicly airing false or fantastical grievances is wrong, especially when designed to sell books. It is also potentially unlawful and defamatory.”
Tensions between the two sisters appear to be running at an all-time high following Jamie’s promotional appearance on Good Morning America, in which she described herself as her “sister’s biggest supporter” and suggested that she “took steps to help” in relation to the conservatorship.
Responding to the interview, Spears said, “She was never around me much 15 years ago at the time… so why are we even talking about that unless she wants to sell a book at my expense.”
Two weeks ago it was also reported that Spears had unfollowed her younger sibling on Instagram. In a scathing new post, she accused Jamie and their mother of not supporting her, writing: “I’m sorry Jamie Lynn, I wasn’t strong enough to do what should have been done… slapped you and Mamma right across your f****** faces!”
Britney went on to say in another post: “Jamie Lynn. I asked myself every day “DOES ANYBODY CARE ??? WTF ??? DO I MATTER ???” I would honestly be very interested to see your pretty face in the setting I was forced to be in and asking yourself “DO I MATTER ???”

Issuing her own statement via Instagram, Jamie wrote that it was “exhausting when conversations and texts we have in private don’t match what you post on social media.”
“Quite frankly the things being said are absolutely not the truth,” she said. “It’s getting harder for me to rationalize to my oldest daughter why our family continues to get death threats, as a result of her aunt’s vague and accusatory posts.”
“Especially when we know she could tell the truth, and put an end to all of it in one second if she wanted to.”
