Troubled pop star Britney Spears has reportedly demanded an entire wing at the California rehab center where she is undergoing treatment be cleared - for her privacy.

Spears, who was admitted to the Promises Clinic in Malibu last Tuesday and re-admitted again on Thursday after checking herself out the day before, doesn't want to mix with other patients, according to press reports.

An insider told British newspaper The Sun, "She wants all the rooms on her wing. It will cost her hundreds of thousands (of dollars)."

Spears was recently visited at the clinic by her estranged husband Kevin Federline and their two sons Sean Preston and Jayden James.
