Britney Spears' father Jamie, who has been coconservator of the star's estate with lawyer Andrew Wallet, on Thursday was given more responsibility for his daughter's affairs, and additional financial control was granted to Brit's brother, Bryan. In a hearing, Commissioner Reva Goetz granted the request for extension, citing signs that Britney's stayed out of trouble (read: dancing, shopping) since Jamie took over. The coconservators requested that their authority be extended until at least March 10, because a psychiatric evaluation of Britney was not ready by Wednesday, as expected. The two were ... given the new responsibility for her taxes, while Bryan Spears was named a trustee of his sister's trust. As for that pesky issue of her so-called manager Sam Lutfi, however, the court has not been able to serve him his restraining order yet. But there's always another hearing for that.
