SHOCKING: Britney Spears’ new documentary reveals that her calls and texts were monitored

According to a New York Times documentary aired on Friday, a security agency hired by Britney Spears' father monitored the pop singer's phone conversations and text messages during the court-ordered conservatorship she has been under since 2008.

Alex Vlasov, a former Black Box Security employee who worked with Britney Spears' team for over nine years, said in Controlling Britney Spears that the company "mirrored" the pop singer's phone on an iPad by signing in to her account.

He informed the filmmakers that he was instructed to encrypt portions of Spears' text messages so that they could be transmitted to her father, Jamie Spears, and an employee of a business management agency he hired.

When Vlasov inquired about the monitoring, he was told that Britney Spears' conversations were monitored "for her own security and safety," and that the court supervising the conservatorship, as well as her lawyers at the time, were "aware of it." According to Vlasov, the surveillance included conversations between Britney Spears and her attorney, Sam Ingham.

Jamie Spears' attorney, Vivian Thoreen, declined to comment on specific claims, but claimed his activities "were fully within the limits of the power placed upon him by the court," and "were done with the knowledge and permission of Britney, her court-appointed counsel, and/or the court."

Jamie Spears' record as conservator – and the court's acceptance of his acts - speak for themselves, according to Thoreen, who claims Jamie Spears assisted his daughter in rehabilitating her career and improving her financial condition.

Jamie Spears established a conservatorship in 2008 to supervise his daughter's personal affairs and about $60 million estate after she had a mental health breakdown. Britney Spears is trying to get the conservatorship removed. In June, the singer of "Stronger" described the contract as "abusive and humiliating."

Jamie Spears, in an unexpected move earlier this month, stated that he supported terminating the conservatorship because circumstances had changed. The lawsuit is set for a hearing in Los Angeles Superior Court on Wednesday. Mathew Rosengart, Spears' new lawyer, stated in a statement that he would look into the new allegations.

The statement stated, "Intercepting or monitoring Britney's conversations, especially sacrosanct attorney-client conversations, marks a shameful and shocking breach of her privacy and civil freedoms." “It would be particularly disgusting to place a listening device in Britney's bedroom.”

Controlling Britney Spears premiered on the FX cable network and on Hulu on Friday night. It comes after the release of the same filmmakers' documentary, Framing Britney Spears, in February, which sparked renewed interest in the case.
