There were reports that the 28-year-old 'Fury' actor was getting help at a celebrity-frequented treatment facility in Hollywood.
"Contrary to previous erroneous reports, Shia LaBeouf has not checked into a rehabilitation facility but he is voluntarily receiving treatment for alcohol addiction," the rep said in a statement.
"He understands that these recent actions are a symptom of a larger health problem and he has taken the first of many necessary steps towards recovery," he added.
The 'Transformers' star was arrested on charges of disorderly conduct, criminal trespass and harassment last Thursday at the Broadway show 'Cabaret'.
