Shia LaBeouf -- Judge Gives Actor High Five For Alcohol Rehab

Shia LaBeouf showed up in a NYC court Tuesday AM to show a judge he is successfully rehabbing himself after getting arrested for disorderly conduct.

Shia brought paper proof he's on track to complete his 6 months of outpatient alcohol rehab ... this after getting arrested for drunkenly disrupting a performance of "Cabaret" last June at Studio 54 in NYC. As he was escorted out of the show he screamed, "Do you know who the f*** I am?" Later at the precinct, he spit at a police officer.

The judge gave Shia a thumbs-up and then said he wanted to see him in March when he completed the rehab classes.

Shia has been spending lots of time working out for his new movie "Man Down."

Man up.
