A lawyer for Britney Spears has stepped up demands for the swift suspension of the singer's father from his role as her guardian, saying he had "crossed unfathomable lines" by reportedly bugging her phone and bedroom.
In a court filing before a hearing on Wednesday, lawyer Mathew Rosengart said a TV documentary released on Friday contained "deeply disturbing allegations" that "magnify the need to suspend Mr Spears immediately".
The New York Times documentary Controlling Britney Spears featured a former employee of a security firm hired by Jamie Spears who said he monitored the singer's phone calls and text messages, including some with her previous lawyer.
A listening device was also placed in her bedroom, the employee said.
Lawyers for Jamie Spears did not discuss specific allegations but said last week his actions were within his authority as a conservator and "were done with knowledge and consent of Britney, her court-appointed attorney and/or the court".
Jamie Spears has controlled his daughter's business affairs since 2008, when he put in place a conservatorship after she suffered a mental breakdown. The arrangement has dictated her personal, medical, performing and financial affairs.
The singer stepped up her efforts in June to break free of the arrangement. In a surprise move earlier in September, Jamie Spears said he supported ending the conservatorship but said there were no grounds to suspend him.
A hearing on the case is scheduled for Wednesday in Los Angeles Superior Court.
