PHOTOS: Mischa Barton is Crazy Beautiful

Mischa Barton makes her first appearance since her release from Cedars-Sinai Medical Center, where she was placed on an involuntary psychiatric hold earlier this month after reportedly suffering a meltdown.

The actress put on a brave face as she arrived at JFK Airport on Wednesday with her dog Ziggy. The star is set to begin filming her new TV show The Beautiful Life, where she will play a catwalk beauty addicted to pills.
