Pop singer Britney Spears (39) has regained her freedom after 13 years under tutelage.

According to consistent media reports, a judge in Los Angeles lifted all guardianship requirements on Friday.

Judge Brenda Penny complied with a request from the singer's lawyers at a hearing.

At the end of September, the judge had already deposed Spears' father as the singer's guardian and appointed a replacement.

The 69-year-old Jamie Spears has been the guardian of his daughter since 2008 after the singer collapsed mentally due to personal and professional problems.

At court hearings in June and July, the singer violently attacked her father in emotional speeches and accused her family and carers that they controlled their lives and enriched themselves with them.
