Britney Spears issues cease and desist letter to sister Jamie Lynn amid new book

Britney Spears has sent a cease-and-desist letter ordering her sister, Jamie Lynn Spears, to stop talking about her.

The ‘Toxic’ hitmaker’s legal team want the ‘Zoey 101’ actress to stop discussing the 40-year-old pop star’s life and struggles when she’s giving interviews to promote her new memoir.

Jamie Lynn is currently on a promotional tour for her new book ‘Things I Should Have Said’, which Britney’s legal counsel said contains ‘misleading and outrageous claims’ about her.

Now, lawyer Mathew Rosengart has written a stinging letter to Jamie Lynn, demanding that she ‘cease and desist from referencing Britney derogatorily’ and threatening ‘all appropriate legal action’ should the actress not comply. 

‘We write with some hesitation because the last thing Britney wants is to bring more attention to your ill-timed book and its misleading or outrageous claims about her,’ the letter 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.’

The letter comes as Britney hit out against Jamie Lynn and her mother Lynne in a fiery Instagram post in which she said she should have slapped them both ‘across their f***ing faces’.

After years under a conservatorship overseen by her father, Jamie Spears, Rosengart stressed Britney will not be ‘bullied’ by anyone any more.

The letter continued: ‘You of all people know the abuse and wrongdoing Britney had to endure during the conservatorship, after initially growing up with a ‘ruinous,’ alcoholic father. 

‘In fact, your own book reportedly states that your father ‘spent most of my life in that cycle of ruinous behaviour. His bouts of drinking caused me periods of torment and sorrow.’

‘As I have previously stated, having endured a 13-year conservatorship that stripped her of civil rights and fundamental liberties, Britney will no longer be bullied by her father or anyone else.’

Jamie Lynn was accused of ‘airing false or fantastical grievances’ to garner publicity for her book and warned her sister will take further legal action if she continues to speak about her and their feud.

The letter, which was first obtained by Page Six, concluded: ‘Britney was the family’s breadwinner and she also otherwise supported you. Publicly airing false or fantastical grievances is wrong, especially when designed to sell books. It is also potentially unlawful and defamatory.

‘Michelle Obama famously said, ‘When they go low, we go high.’ And to Britney’s great credit, that is exactly what Britney is going to do, for the time being.

‘You recently reportedly stated that the book was ‘not about her.’ She takes you at your word and we, therefore, demand that you cease and desist from referencing Britney derogatorily during your promotional campaign.

‘If you fail to do so or defame her, Britney will be forced to consider and take all appropriate legal action.’

News of the letter comes as Britney hit out at her sister and mother in a wild Instagram post in which she said she should have ‘slapped’ her family members ‘across your f***ing faces.’ 

In her since-deleted post, 40-year-old singer–songwriter seemed to take aim at her sister Jamie Lynn Spears, 30, for having gotten a cushier upbringing and a starring role on TV when she was just a child.

She also lambasted her mother Lynne Spears for not being supportive to her in the wake of her breakup with Justin Timberlake.

Sources close to Jamie Lynn told TMZ that she was ‘disturbed’ and ‘upset’ by the Instagram video, and claimed Jamie Lynn believes Britney has ‘immense…
