LOS ANGELES — Britney Spears has been freed from her father. And she could be freed entirely from court control within weeks. In a major victory for the pop star, a judge on Wednesday suspended the singer’s father from the conservatorship that has controlled her life and money for 13 years, saying the arrangement “reflects a toxic environment.” Los Angeles Superior Court Judge Brenda Penny agreed with a petition from Spears and her attorney that James Spears needs to give up his role as conservator.
