Britney Spears is seeking to make changes to her conservatorship, which has been in place since 2008. The 38-year-old singer is asking that her father, Jamie Spears, be removed as her conservator, according to court documents obtained by Entertainment Tonight. A conservatorship is put in place when a judge appoints a responsible person or organization – the "conservator" – to care for another adult who cannot care for himself or herself or manage his or her own finances, according to the California court system. According to the court documents filed on Monday, Spears wants Jodi Montgomery to become her permanent conservator. Montgomery, Spears' longtime care manager, was appointed her temporary conservator in 2019 when Jamie Spears faced health issues. Montgomery's role as a temporary conservator expires on August 22, ET reports.Spears canceled her new Las Vegas residency when her father was hospitalized last year. The mother of two said in a statement she would be on an indefinite work hiatus "to devote all of her time to her family and their efforts to care for her father during his recovery." Fans of Spears felt her father's hospitalization gave her the opportunity to take the reins and cancel her concerts without his input. This fan theory is just one part of the extensive "Free Britney" movement, which fans created to raise concerns about Spears' behavior and conservatorship. Many fans believe Spears is being controlled by her father, is a prisoner in her own home, and has been trying to use her Instagram to subtly ask the public for help. The pop star's father, who is 68, recently spoke about the conservatorship and the Free Britney movement in a Page Six interview. He called the movement "a joke." "All these conspiracy theorists don't know anything. The world don't have a clue," he said. "It's up to the court of California to decide what's best for my daughter. It's no one else's business." He also denied rumors that he or anyone else is skimming money off of Britney's estate. "I have to report every nickel and dime spent to the court every year," he said. "How the hell would I steal something?" He said he loves his daughter and all his kids, and added, "this is our business. It's private."
