Macaulay Culkin, who testified last month in support of Michael Jackson, was back in court Wednesday, this time for his own problems.

He pleaded guilty in an Oklahoma City courtroom to misdemeanor charges of possession of medication without a prescription and marijuana. Culkin was given a 1-year deferred sentence on each charge.

He was arrested in September after he was caught with the drugs while sitting as a passenger in a car.

Culkin is best known for his memorable roles as a child in the Home Alone movies.
