Officers pulled over Ronson's black Porsche Targa when they noticed her driving 19 miles over the 70 m.p.h. speed limit.

"Speed was why she was stopped, but she was arrested on [two] misdemeanors of driving under the influence," an officer told Us Weekly. "When she was stopped, she showed signs of being impaired. [The officer] gave her balance tests and she showed signs of alcohol intoxication."

Ronson, who famously dated Lindsay Lohan from 2008 to 2009, was alone at the time of the arrest. "She was friendly and talkative," an officer said. "She was cooperative throughout the whole ordeal."
