star Mischa Barton continue hospitalized

Mischa Barton, currently hospitalized at Cedars-Sinai Medical Center in Los Angeles under psychiatric evaluation, known as a 5150 hold, could be released as early as Saturday, or held longer, experts say.

Mischa Barton remains hospitalized, two days after Los Angeles police say they escorted her from her home with an undisclosed medical problem. Her publicist, Craig Schneider, says in a statement that the 23-year-old actress remains in the hospital under doctor's orders.

Police say they removed Barton from her home on Wednesday afternoon for a medical problem. The department will not say what it was.

Schneider's statement also does not address Barton's condition.

The actress rose to fame as a star on Fox's teen drama "The O.C." She was arrested in December 2007 and later pleaded no contest to a drunken driving charge.
