Shia LaBeouf and his Lawless leading man Guy Pearce posed for pictures on the red carpet at their LA premiere last night. The screening brought out many celebs, though Shia mainly had eyes for his girlfriend, Karolyn Pho. Diddy smiled for the cameras with his son Quincy, and Liberty Ross, not wearing her wedding ring, also checked out the screening. Shia brought the picture west after last week's NYC premiere of Lawless, where he told us about bonding with costars Jessica Chastain and Tom Hardy over moonshine. The picture arrives in theaters next Wednesday on Aug. 29, so Shia and company have a few more days to talk up the Prohibition-era action movie. Another topic that's getting lots of attention is Shia's next role — his part in Lars von Trier's Nymphomaniac apparently requires actual sex scenes.
