Britney Spears is expected to address a judge overseeing the conservatorship that has controlled the pop star's money and affairs since 2008.
If Los Angeles Superior Court Judge Brenda Penny does not make a last-minute decision Wednesday to seal the proceedings, Spears will be heard in open court for the first time in the 13-year conservatorship.
The hearing has been eagerly awaited by the fans in the so-called #FreeBritney movement, who feel she is being controlled unfairly against her will and are likely to gather outside the courthouse in large numbers.
Spears has sought a greater say over who runs the conservatorship and has asked that her father, who had extensive power over her life and money for most of its existence, be removed.
