Girl, you need to settle down!
A photographer approached Mischa Barton at SXSW and she was NOT having any part of it!
She and her friends immediately went on the defense and some sort of scuffle took place. It's kind of hard to see on the vid because Mischa and her friends pushed the camera away.
Watch it all go down (above).
What do U think? Was Mischa overreacting or did she have the right to the push the camera?
