Shia LaBeouf -- Hey, Judge ... I Completed Alcohol Treatment!

Shia LaBeouf is almost home free in his disorderly conduct case after he went into a Manhattan court Friday morning and handed a judge proof he completed his alcohol treatment program.

Now all Shia has to do is stay out of trouble for six months, and the case will be dismissed.

The whole thing stems from Shia's arrest last June after he drunkenly disrupted a performance of "Cabaret" at Studio 54 in NYC, during which he screamed at security, "Do you know who the f*** I am?"

He also allegedly spat at cops while being booked at the police station.

Shia sported his new rattail 'do in court today. He was not ticketed.
