Mischa Barton at JFK airport in New York (7/28)

E! Online's Ted Casablanca is claiming that Mischa was forcibly committed into a mental hospital two weeks ago because she tried to kill herself -- and not in the "if I eat one more piece of cake, I'll just die" kind of way:

Mischa Barton's recent hospital stay was due to "suicidal" actions, claims a source very close to the star's drama. Also, the insider asserts, the attempt may have coincided with Mischa's bosses at the CW's The Beautiful Life deciding they no longer desired her services.

"She tried to kill herself," claims the source close to Barton, who also asserts that Mischa had also been let go—and later rehired—from the soap.

"She was being crazy that day [when she went to Cedars Sinai Medical Center]," says another knowledgeable source, who had direct dealings with Ms. B right before she entered Cedars in Los Angeles, reportedly involuntarily under a psychiatric hold, for "medical reasons."

According to Casablanca, a few of Mischa's friends are claiming that she was committed because she was downtrodden from a tooth ailment. In other news, Mischa Barton's friends are fucking idiots. A tooth ailment? Really? That's the best they could come up with? Why not just say she was downtrodden because someone broke into her house and stole her "Best Actress" Oscar? It would have been just as believable.
