Britney Spears' lawyer accuses of Jamie Spears 'horrifying invasions of his adult daughter's privacy'

Britney Spears' lawyer has filed legal documents accusing her father of having "engaged in horrifying and unconscionable invasions of his adult daughter's privacy".

Mathew Rosengart lodged documents with the Los Angeles Superior Court today in which he declared "the chickens have truly come home to roost" following a "bombshell exposé" by The New York Times, which claimed Jamie Spears had allegedly recorded his daughter's communications without her permission.

In a filing obtained by the New York Post's Page Six column, the lawyer stated: "Specifically, the Times reported that he and others 'ran an intense surveillance apparatus that monitored [Ms Spears's] communications' and also evidently captured attorney-client communications with her prior lawyer, which communications are a sacrosanct part of the legal system."

He also claimed that what was "even more shocking" was that Jamie - who is co-conservator of the 39-year-old pop star's affairs -" crossed unfathomable lines" by having allegedly illicitly "captured audio recordings from Britney's bedroom, including private communications with her children", which he branded a "disgraceful violation" of the Circus hitmaker's rights.

The lawyer told the outlet in a statement: "Unauthorised recording or monitoring of Britney's private communications — especially attorney-client communications, which are a sacrosanct part of the legal system — represent an unconscionable and disgraceful violation of her privacy rights and a striking example of the deprivation of her civil liberties.

He added, "Placing a listening device in Britney's bedroom would be particularly horrifying and corroborates so much of her compelling, poignant testimony. Mr Spears has crossed unfathomable lines."

The documents pointed out that Britney's home state of California is a "two-party" consent area, meaning both those doing the recording and those being recorded need to give authorisation.

And Mathew claimed the allegations will distract Jamie from acting in Britney's best interests, adding it to his arguments as to why he wants him removed as conservator by September 29, when a court hearing is due to take place.

He argued: "As a result of these deeply disturbing allegations, Mr Spears will inevitably be focused over the next several days and weeks on defending his own interests not his daughter's (yet again)."

Mathew - who has previously argued Jamie should be removed from his post because he could "impede" negotiations for Britney and her fiance Sam Asghari's prenuptial agreement, he has a poor financial history, and both his client's mom, Lynne Spears, and temporary conservator Jodi Montgomery also want him out - wants to question the Stronger singer's dad but expects he will invoke the Fifth Amendment right against self-incrimination.

He said in the filing: "Even assuming Mr Spears were to invoke the Fifth Amendment at his deposition, there are questions he still would be required to answer, which would inform the Court's decisions on these accounting and financial issues at an evidentiary hearing in the future.

"Relatedly, the mere invocation of the Fifth Amendment would be highly illuminating and would also permit the Court or jury to draw an adverse inference based upon that invocation."

This comes after a new documentary claimed Britney Spears' phone and internet use were monitored by her father.

The 'Toxic' singer - who has been outspoken about wanting Jamie Spears to lose his position as conservator of her affairs - reportedly "worried" her team when she requested a new iPhone and her security staff were asked to put "parental control" on the device so other people could gain access to her texts, calls, and browser history.

Speaking in new documentary 'Controlling Britney Spears', Alex Vlasov, who worked for Black Box Security from 2012 to 2021, said: “Britney wanted to get an iPhone … and that was a big deal. Everybody was worried.

“[My boss] Edan [Yemini] approached me and asked me, ‘Is there any monitoring services for an iPhone that you are aware of?’ And I’m like, ‘What do you mean?’ And he’s like, ‘Well, parental controls. Is there any way you can put parental controls on an iPhone?'

"And that’s when Edan explained to me that Britney’s communication is monitored for her own security and protection.”

Alex questioned "the legality" of the request, and was told the court were "aware" of the monitoring of her communications, which eventually led to Britney's phone being cloned onto an iPad, which was kept in a safe.

He continued: "[Edan] said, ‘Yes, the court is aware of this. Britney’s lawyer is aware of this. This is for her safety. It’s for her protection'.

“And then Robin [Greenhill of Britney’s management team at Tri Star Sports & Entertainment Group] came up with the idea of, ‘Why don’t we just take an iPad, sign in with an iCloud on there, the same iCloud that Britney would use on her phone, and that would mirror all activity?’ You would be able to see all messages, all FaceTime calls, notes, browser history, photographs.

“Their reason for monitoring was looking for bad influence, looking for potential illegal activity that might happen, but they would also monitor conversations with her friends, with her mom, with her lawyer Sam Ingham. If there’s anybody that should be off limits, it should be Britney’s lawyer."

Tri Star Sports & Entertainment group branded the allegations "false", but Jamie's lawyer, Vivian Lee Thoreen, insisted his actions "were done with the knowledge and consent of Britney, her court-appointed attorney and/or the court.”

And Edan's lawyer said: “Black Box have always conducted themselves within professional, ethical and legal bounds, and they are particularly proud of their work in keeping Ms. Spears safe for many years.”
