Britney Spears has asked a judge to end the conservatorship that has controlled her life and finances for the last 13 years, telling a US court she just 'wants her life back'.
Addressing a hearing in LA, the singer says she feels she has been 'exploited'.
Her father has been the guardian of her affairs since 2008, and lawyers for Jamie Spears dismiss criticism of his actions.
In a 20-minute speech, Ms Spears told the court: "This conservatorship is doing me way more harm than good. I deserve to have a life.
"I feel ganged up on and I feel bullied and I feel left out and alone. And I'm tired of feeling alone."
She claims the arrangement forces her to use birth control, preventing her from having more children.
Judge Brenda Penny said it "took a lot of courage" for the singer to speak out about the issues.
Jamie Spears' legal team, meanwhile, argued that Britney's fortune - estimated to be about $50 million - remains vulnerable to fraud and manipulation
Yesterday's hearing was the first time the singer has revealed details of her conservatorship in an open court.
A number of celebrities have shared messages of support for the singer, including Justin Timberlake and Mariah Carey.
The public debate around Ms Spears' conservatorship has reignited following the recent broadcast of the Framing Britney Spears documentary.
A final decision on the court case can't be made until a formal request to end the conservatorship is lodged with the court.
Further proceedings on the matter are expected to be private, following a request from the singer's lawyers.
On Newstalk Breakfast, Harriet Alexander - senior online reporter for The Daily Mail - described more of what happened in court yesterday.
Harriet said: "She really gave this incredibly emotional, passionate telling of what her life was like under this conservatorship.
"She said she was forced against her will to have an IUD implanted, so she couldn't have any more children. She said she wanted to get married to her boyfriend, but that was not allowed.
"She said she was put on some incredibly strong drugs to try to control her mental health... that she was being forced to perform, and she was miserable the entire time."
