Shia LaBeouf receiving treatment for alcohol addiction

A representative for the star told 'Access Hollywood': "Shia LaBeouf has not checked into a rehabilitation facility but he is voluntarily receiving treatment for alcohol addiction. 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."

The 'Transformers' star was charged with harassment, disorderly conduct and criminal trespassing last Thursday after he allegedly began yelling offensive language and slapping people's bottoms midway through a Broadway performance of 'Cabaret' at Studio 54.

He was also spotted arguing with a homeless man over a baseball cap on the streets of the city a few hours before his arrest.

A source said the actor - who was wearing a bright blue T-shirt with a huge hole on the shoulder - was acting as if he knew the man, but seemed "whacked out" and was making no sense.

Shia is expected to appear in court in relation to his New York charges on July 24.

Meanwhile, Shia's friends and family became increasingly worried about the star earlier this year after he stormed out of a 'Nymphomaniac'

press conference in Berlin, before arriving on the red carpet for the film's German premiere wearing a paper bag on his head that read, "I am not famous any more."
