His attorney entered the plea on Monday in Los Angeles. The performer, whose real name is Curtis Jackson, was silent during the hearing.
He was charged after Daphne Narvarez reported that he had trashed her Toluca Lake condo and kicked her during an argument. Police said property worth $7,100 was destroyed.
Jackson was ordered to return to court on Sept. 4 and told to stay away from Narvarez, not make calls to her, and to get rid of his weapons.
