Britney Spears’ parents have said that they fear for her life, after the pop star was discharged from hospital against the recommendation of her psychiatrist.

In a joint statement, Jamie and Lynne Spears said they were ‘extremely disappointed’ to learn that their troubled daughter had been released.

Britney was discharged from the UCLA Medical Center in Los Angeles, where she had been undergoing psychiatric evaluation, a week earlier than expected.

“As parents of an adult child in the throes of a mental health crisis, we were extremely disappointed to learn that over the recommendation of her treating psychiatrist, our daughter Britney was released from the hospital that could best care for her and keep her safe,” the statement said.

“We are deeply concerned about our daughter’s safety and vulnerability and we believe her life is presently at risk. There are conservatorship orders in place created to protect our daughter that are being blatantly disregarded. We ask only that the court’s orders be enforced so that a tragedy may be averted.”

The 26-year-old’s release came after a series of legal developments in which her father fought for control of the pop star and her estate, a companion was ordered to stay away from her, and her mother vividly described her daughter’s fragile state and the strange behaviour that led to her being taken to hospital on January 31.

The singer has been in a spiral of increasingly bizarre behaviour since November 2006, when she filed for divorce from Mr Federline.
