Britney Spears will likely spend the next two weeks in a psychiatric centre's padded cell, it has been claimed.
According to reports the Disturbed singer has been declared a danger to herself or others by staff at the UCLA Medical Centre.
The 26-year-old had initially been set to stay at the Los Angeles centre for 72 hours after being sectioned last week.
But a hospital source told People magazine: "Britney Spears' hospitalisation has been extended to an additional 14-day hold."
Television pictures showed Britney being hospitalised for the second time in a month in January, and her latest medical containment will see her miss yet another custody hearing over sons Jayden James and Sean Preston.
Britney's ex-husband Kevin Federline currently has full custody of the boys.
Meanwhile it has been claimed that the singer's parents have reported a theft of many of their daughter's possessions in the hours after she was sectioned.
Press reports claim Lynne and Jamie Spears blame Britney's manager Sam Lufti for the thefts.
But he retorted: "First they take her kids, then her home and money. Britney does not have anything left."
