Law enforcement officials have confirmed to X17online that the actor was busted just after 3am while on the 101 freeway near Woodman Ave.

After failing the sobriety test, Klein, 31, was put in the backseat of a CHP unit and taken to a Van Nuys-area jail where he was booked.

Hard to believe that he and Katie Holmes were once a hot item!

Stay tuned for the addition of Klein's mugshot to the Hall of Shame.
