Will Smith's actor son Jaden has reached out to Shia LaBeouf and offered the troubled actor his help.

The Transformers star has sparked fears for his wellbeing in recent weeks following a series of headline-grabbing stunts, including walking the red carpet at a film premiere with a paper bag over his head and setting himself up in a bizarre live art installation in Los Angeles.

Fans have been queuing for hours to get into LaBeouf's gallery for a one-on-one session with the actor, and young star Jaden Smith joined the throng on Sunday (16Feb14).

Smith failed in his attempt to get into the gallery to see LaBeouf, so he has reached out to him via Twitter.com to send a message of support, writing, "I waited in line today on Beverly Blvd to see (Shia LaBeouf) I never got see him but I had a very important message to deliver... It was a message that only could be understood artist to artist... I'm here for you I believe in what your (you are) doing... I'm here if you need a fellow insane person to talk to. But I'm seriously here not like one of those 'I'm here for you's' that everybody says."
