It’s a rough way to start the morning, and it shows all over Samantha Ronson’s face.
The celebrity deejay put on a smirk in her mug shot following her arrest at 10:31 a.m. Monday in the California desert for investigation of driving under the influence.
Ronson, 33, the driver, “displayed signs of alcohol intoxication” and after field sobriety tests was arrested, booked at the sheriff’s jail and released.
“She was cooperative throughout the entire contact,” says the police report.
