The 33-year-old DJ – who was arrested last Monday while driving her black Porsche back to Los Angeles from a gig in Las Vegas – has been charged with two counts of DUI, driving under the influence and driving with a blood alcohol level over .08.
 
If she were to be convicted, she could face six months in prison, but the majority of first offenders usually get probation, according to TMZ.com.

Samantha – who is best known for her relationship with Lindsay Lohan and as the brother of record producer Mark Ronson – was arrested at 10:30am after she refused to take a breath test when asked.
