BRITNEY SPEARS POSTS TOPLESS PHOTO AMID CONSERVATORSHIP BATTLE
The former teen star is currently fighting to have her father removed from her conservatorship. James P. Spears, also known as Jamie, controlled the singer's finances since 2008.
She recently argued she "shouldn’t be in a conservatorship" in a bombshell testimony that reignited the #FreeBritney movement.
In her 24-minute address to the court in June, the star claimed that her father "loved" the control that he held over her. She called the conservatorship "abusive" and said it's left her "traumatized."
She claimed that she was once locked in a small Beverly Hills rehab center and is blocked from removing contraception from her body.

"I am not happy, I can’t sleep. I’m so angry, it’s insane. And I’m depressed. My dad and anyone involved in this conservatorship, including my management… they should be in jail," Spears said at the time.
The next hearing about Spears' controversial conservatorship will take place on July 14.
