Britney Spears said she wanted her father charged with conservatorship "abuse" on Wednesday in the latest court hearing over the controversial arrangement.
The 39-year-old pop star demanded that her father Jamie Spears be stripped of legal control of her career and finances as she addressed a Los Angeles court for the second time in less than a month.
In a victory for the singer, Judge Brenda Penny, who oversaw the hearing, permitted her request to hire a lawyer of her choosing.
Spears has chosen Mathew Rosengart, a high-powered Hollywood lawyer and former federal prosecutor, to represent her in what is likely to signal a more aggressive approach to ending the conservatorship.
But his request that Spears’ father be removed as her conservator was rejected.
Spears spoke publicly for the first time last month about the court-approved legal arrangement that was first put in place in 2008 when she suffered a mental health breakdown.
During the June court hearing, she argued the conservatorship had an intolerable level of control over her life, claiming among other things that she had been forbidden from having children and made to take lithium, a powerful mood stabiliser drug with serious side effects.
On Wednesday, Spears initially told the judge she wanted the courtroom cleared before she spoke but then changed her mind.
Among the litany of complaints she made about the conservatorship were claims that her hair vitamins and coffee had been taken from her.
"Ma’am, that’s not abuse, that’s just f—ing cruelty," a tearful Spears told Judge Penny. "Excuse my language but it’s the truth."

In response to his daughter’s claims, lawyers for Jamie Spears have previously said: "He is sorry to see his daughter suffering and in so much pain. Mr Spears loves his daughter and misses her very much."
The singer reiterated that she wanted the conservatorship to be terminated without the need for a medical assessment, but indicated her top priority was ousting her father from his role while allowing co-conservator Jodi Montgomery to remain.
But she went on: "My dad needs to be removed today and I will be happy with Jodi helping me," she told the court, breaking into tears at times.
The singer, who took a short break to compose herself, demanded her father be removed from the conservatorship and be charged with "conservatorship abuse".
Spears said she has "extreme abandonment issues" and was "extremely scared of my dad".
Apparently recalling her childhood, she said she feared the 69-year-old, a recovering alcoholic, was always going to "show up drunk somewhere and embarrass me".
"I’m here to press charges. I’m angry and I will go there," she said.
Concluding her address, which she said she had written down, the singer said: "I want him (her father) removed and I want a court-appointed lawyer and I want investigations."

The hearing took place inside a packed court in downtown Los Angeles, with around 60 masked journalists and fans in attendance.
Spears’ court-appointed lawyer, Samuel Igham, stepped down after the singer’s called the conservatorship abusive, stupid and embarrassing in her June testimony.
An estate-management company that was supposed to oversee her finances also withdrew from its post.
Outside the courthouse, dozens of fans held a rally, chanting "Free Britney" and cheered as Judge Penny ruled Spears could select her own lawyer.
Among them was the Republican congressman Matt Gaetz, who called for changes to legal arrangements like the one governing Spears’ finances and personal life.
"Every time there is a hearing in this case that does not result in freedom for Britney Spears and dissolution of her guardianship, it is a black eye on the American justice system," Mr Gaetz said.
