Mischa Barton's new TV show has been postponed.
Shooting on 'The Beautiful Life' was due to start on July 22, but it has been delayed after it was claimed sets for the show have not been completed in time.
It has been denied Mischa's hospitalization under an involuntary psychiatric hold order at Los Angeles' Cedars-Sinai Medical Center last week is to blame for the move.
Mischa's publicist admits production can't begin without her, and insists the actress must fully recover before she returns to work.
The representative reportedly said: "Her participation will ultimately be contingent upon her progress and doctor's orders."
Mischa was placed under a 5150 hold - meaning she poses a danger to herself or others - last Wednesday after friends reportedly became worried she was suicidal. It has been alleged the actress has been using drugs and alcohol to cope with her money problems and stuttering love life.
Filming is now scheduled to begin on July 31.
'The Beautiful Life', which is produced by Ashton Kutcher, focuses on a group of models living together in New York.
Mischa, 23, will play a supermodel who is desperate to be successful and struggles to cope with the pressures of working in the fashion world.
