Shia LaBeouf is sober, and if he stays that way, we can thank Brad Pitt.

The two are set out to head out on a worldwide media blitz for their upcoming World War Two movie Fury, and according to sources, Shia wants to stay on the straight an narrow because he's terrified of embarrassing Brad.

TMZ says Shia is taking his outpatient alcohol treatment program "seriously" and he's ready to dive back into the acting game.
