The female passenger riding with Shia LaBeouf when he flipped his car over the weekend has been identified as Australian actress Isabel Lucas, who's co-starring with Shia in Transformers 2, according to E! News. We don't think being his crash test dummy is in her job description. Luckily, Isabel was unharmed in the crash and has already returned to filming. Shia, too, is "doing fine," his mom says. But he won't be for long -- he's scheduled to appear in court in August to face misdemeanor DUI charges associated with the crash.
