(CBS) - Samantha Ronson, the ex-girlfriend of actress Lindsay Lohan,  was arrested Monday morning on suspicion of driving under the influence outside of Baker, Calif., according to a report. 

The 33-year-old DJ was on her way home from a late-night show at the Palazzo hotel in Las Vegas. According to police, she was pulled over in her Porsche near Baker, over 100 miles northeast of Los Angeles, at 9:48 a.m. by the California Highway Patrol, reports E! News.  

"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."

She was immediately arrested then sent to the San Bernadino County Jail to sober up for a few hours before leaving around 5:30 p.m., reports E!
