Judgment Day Coming Soon for 'Hannah Montana' Star

Mitchel Musso -- who starred alongside Miley Cyrus on "Hannah Montana" -- has been charged with 2 counts of drunk driving stemming from his arrest in Burbank, CA earlier this week.

Law enforcement sources tells TMZ ... the Burbank City Attorney has charged Musso with driving under the influence of alcohol and driving with a blood alcohol level of .08 or higher -- both misdemeanors.

If convicted on both counts, 20-year-old Musso faces a maximum of 6 months in jail and a $1,000 fine. The reality, however, is that no first-time DUI offender in LA County is sentenced to jail ... unless there are aggravating circumstances, and our sources says there are no aggravating circumstances here.

Musso will almost certainly be given probation, along with a mandatory alcohol education class and fines.

TMZ broke the story ... Musso was pulled over at 3:43 AM Sunday ... after he allegedly failed to slow down for cops who were directing traffic for an unrelated accident. Cops suspected he was hammered and placed him under arrest.
