Mischa Barton out and about in Beverly Hills (7/3)

It was revealed earlier today that Mischa Barton was removed from her home by police yesterday in LA and taken to an undisclosed location. Access Hollywood is now saying that Mischa was placed on an involuntary psychiatric hold (5150 hold) at Cedars-Sinai Medical Center:

The source claimed that Barton was placed under Section 5150 of the California Welfare and Institutions Code by police and transported to Cedars-Sinai.

According to the code, authorities can hold a person involuntarily if they present a danger to themselves or others, are gravely disabled or suffer from a mental disorder.

A rep for the actress confirmed to Access that Barton will not attend the world premiere of her new film, “Homecoming,” which happens Thursday night in New York City, but released no further details on the star.

Of course this psychiatric hold is the same thing that happened to Britney Spears last year, so Mischa's in good company. Wait, Mischa has millions of dollars in the bank, residuals from four #1 albums to fall back on, and a future, right? No? OK, maybe it's not exactly the same. But Mischa is inheriting an '89 Ford Taurus from her grandma, so she's got that going for her, which is nice.
