Shia LaBeouf's recent erratic behaviour is reportedly down to a build-up of pressure from being a child star.
The actor's 2008 'Holes' co-star Siobhan Fallon Hogan believes his reckless actions have been spurred on his inability to deal with fame from such a young age.
Siobhan, who played Tiffany Yelnats in the Disney movie, told the New York Post newspaper: "I think there's a ton of pressure when you're in the acting business. It's hard growing up acting -- being a child actor. There's pressure to act the right way.
"And there's so much attention from the press that, if you make one wrong move, it's under a microscope. I can see that being hard for him."
The 'Transformers' star - who shot into the limelight at the age of 14 when he was cast in the TV series 'Even Stevens' - was arrested at a Broadway theatre earlier this week for yelling offensive language and slapping people's bottoms during a performance of 'Cabaret' at Studio 54 in New York City.
Shia was charged with harassment, disorderly conduct and criminal trespassing, and is set to appear in court on July 24.
It's the latest in a series of incidents which have seen the troubled former child star making headlines worldwide.
Pictures have now emerged, taken shortly before the Caberet incident, of Shia apparently chasing a homeless man around Time Square demanding what looked like a McDonalds bag.
A video has also appeared of the actor trying to start a fight outside a New York strip club.
Earlier this month, the hunk was also reportedly banned from The Local Peasant in Sherman Oaks, California, after he was allegedly caught peeing up against a wall.
Meanwhile, earlier this year, Shia 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."
Meanwhile Liza Minnelli has kindly sent the DVD of Cabaret to the actor following his removal from the performance.
A spokesperson for Minelli, Scott Gorenstein told E! News yesterday that he sent the movie on behalf of Cabaret star saying “I figured he may want to find out how it ends.”
