According to a new report, Britney Spears' father revealed that his daughter suffers from * dementia, while presenting documents to control her finances over a decade ago.

The publication of this bomb news will be discussed in an upcoming BBC documentary about the 39-year-old singer. The documentary will be released soon and is called "The Battle for Britney". The news was reported by The Sun.

The 68-year-old, Jamie Spears, is said to have documented dementia as a reason for taking control of his daughter's property, according to documents shown in the documentary.

Jamie has been taking care of his daughter since her mental health problems in 2007.

Members of the #FreeBritney movement, who believe Britney is being unfairly controlled by her father and her team, have been demanding the removal of Jamie Spears as Britney's caretaker for some time.
