Thanks to her "Piece Of Me" tour from July to October last year, Britney is now worth 2.5 million dollars more than it was at the end of 2017.
Britney's finances will all be revised as the investigation into its conservation continues.
The star is currently locked in a legal battle with her father Jamie Spears because she asked to be freed from her conservatory – which has seen him control her finances, her professional and private life since 2008.
Britney turned to the courts in May to end the conservatory after claiming that Jamie had committed to a mental health facility against her will and had forced her to take prescription drugs.
The judge who chaired the case has since ordered an in-depth investigation of all the people who take part in the Britney conservatory in order to properly assess whether the restrictions on the singer should be relaxed or modified.
The supervised court investigator will conduct extensive interviews with all the people involved in a conservatory case, including guardians, conservators, doctors, and even law enforcement officers who have had contact with the subject.
The investigator will also examine the medical and financial records, including custody agreements involving her two children, Sean, 13, and Jayden, 12, with her ex-husband Kevin Federline, and contractual obligations.
Following the court case, the singer's fans started the social media campaign under the "#FreeBritney" hashtag to demand the end of the conservatory.
