Britney Spears has said that her family treated her worse than a "death row" inmate during her conservatorship as she continued her feud with sister Jamie Lynn.
The 40-year-old pop star - who was locked in a conservatorship governed by her family from 2008 until 2021 - claimed that Jamie Lynn "did nothing" to help her and is "hurt" by previous accusations made by her sister.
During promotion for her autobiography Things I Should Have Said, Jamie Lynn told Nightline that her sister "locked her in a room with a knife" as she exhibited "erratic behaviour", to which Britney called her "scum" on social media.
In taking to Twitter for a new open letter, Britney wrote: "Jamie Lynn ...I don't think your book is about me at all ... I said some harsh things because you obviously hurt me by the things you are making up about me!!!"
The legendary performer had previously said that Jamie Lynn - who is known for appearing on children's television in the mid-2000s - "never had to work for anything", but retracted that comment in her latest post and went on to state that she is "shocked" that their father Jamie is "not in jail" for the role he played in controlling her multi-million-dollar fortune for over a decade.
