Last summer, rehab junkie Mischa Barton was seen stumbling out of a minivan, sucking on a cigarette almost as desperately as she subsequently sucked the joy out of Ashton Kutcher's primetime flop, The Beautiful Life: TBL. (We kid, we kid: there was no joy to suck from The Beautiful Life in the first place.)

But this? This is so much better: Mischa puffing on joint* while cruising the streets of LA in a vintage Cadillac convertible (follow the link). According to reports, this comes after hours of Barton chatting on her cell behind the wheel, which is technically more illegal than smoking pot in California. That girl is all class.

*Yeah, we know she could be smoking a cigarette that she rolled herself. We also know that red could be her natural hair color.
