Mischa Checks Into Image Rehab

After being popped for DUI last week, Mischa Barton has to work on her reputation with the public -- and what better way to do that than to play with a couple of cute dogs?

Photogs "surprised" the former "O.C." star in a Beverly Hills park over the weekend, where she was dropped off by a friend. No driving for her!

After hamming it up with Ziggy and Charlie for a few minutes, Mischa headed home. Mission accomplished!
