It doesn't look like pop singer Britney Spears will be getting time off for good behavior. Despite pulling it together, the 28-year-old mother-of-two will remain under father Jamie's thumb indefinitely. Even though the "Toxic" singer has made an incredible career comeback and has come a long way from the days of mega meltdowns and head shavings, sources say she's still not ready to be the master of her own domain. A source tells Radaronline.com, "Britney won't be in court for the hearing. It seems highly unlikely that the conservatorship will end by the end of summer. Britney's just not ready yet. She has her good days and bad days. Britney has complex issues on a personal and professional level, and that is the reason the conservatorship is still in place." With the protective plan in place, Spears' papa controls the purse strings, along with her medical affairs. Radaronline.com also reports that it's Commissioner Reva Goetz who has the ultimate say as to when the daddy daycare comes to an end -- and that won't be done until a formal hearing is held, which doesn't appear to be anytime soon. Father Jamie took control of Spears' affairs back in 2008, and Spears has since regained her star status.
