Mischa Barton, what happened to you?

Seriously, what happened to her? As you might know it, Mischa Barton has recently been put under psychiatric supervision… similar to what happened to Britney Spears in the past.

Now I'm wondering… where did it go wrong for Mischa Barton? When she started playing in The OC, she very soon became one of the Hollywood's most beautiful girls:



However, recent photos of Mischa are showing me that her weight was going up and down in a matter of weeks… and btw she looked extremely unhealthy to me:




Ouch.

I heard that Mischa started to go downhill the moment when she decided to leave The OC. Some say that she believed that she was bigger the show lol. All of her movies flopped as well.

There are some rumors that her friends, for example Nicole Richie dumped Mischa when she partied excessively.

I just saw a video clip where paparazzi asked Rachel Bilson if she has spoken to Mischa, and Rachel replied: "I haven't spoken to her".

I mean nobody knows what happened to Mischa Barton, yet according to her rep, Mischa Barton is "improving and still under care, with the intentions of being able to resume production on The Beautiful Life next week."

I'm wondering what happened to Mischa...
