Mischa Barton was spotted smoking a funny looking cigarette on Monday in Los Angeles while showing off her new blue classic convertible Cadillac.
The O.C. alumna was seen puffing away before heading into Joan’s on Third for a late lunch with a mystery male friend.
Making things worse: Cameras captured video of Mischa smashing over a curb and then backing the big Caddy out into the middle of the street to get back on the road. (Go to RadarOnline.com to watch.)
Mischa was arrested in December 2007 for DUI. Her career has stalled since.
