That's One Cocky Mugshot, Samantha Ronson!

Someone seems pretty pleased with themselves. Didn’t know DUIs were something to smirk over!

As we reported, Samantha Ronson was arrested yesterday in California for driving drunk. She was on her way back for Las Vegas when the cops pulled her over … at 10:30 in the morning.

Doesn’t seem to have phased her much!

Check that attitude, honey. It will do you no good!
