Mischa Barton was arrested for DUI a few times in the past and she just never learns. Or she just doesn’t care anymore, especially her career is going nowhere as of now. So yesterday, the actress was driving around LA in her convertible, while puffing on a joint. Yes, out in the open. Perhaps she’s just waiting to be arrested at that point, but she got lucky. Or not. So, we all could pretty much guess where this is going. Mischa meltdown, baby!
