Shia LaBeouf Busted on DUI

Shia LaBeouf, in trouble again and this time it's really serious. TMZ has learned he's been arrested for suspicion of DUI.

Law enforcement sources tell us LaBeouf was involved in a car accident at about 3:00 AM at the corner of La Brea and Fountain in Hollywood. We're told Shia made a left turn in front of another car and the two collided, causing Shia's car to roll.

Paramedics were called to the scene and both parties were taken to a local hospital, but no major injuries were sustained.

LaBeouf was placed under arrest on suspicion of felony DUI after we're told he exhibited "outward signs" of intoxication at the scene.
