Let's hope no one was hurt. TMZ is reporting that Lindsay Lohan is in the ER after crashing her Porsche into the back of an 18-wheeler in Santa Monica.

Apparently Lohan and her assistant weren't taken by ambulance to the hospital, so it doesn't sound so serious, but this crash sort of fits the "one-step forward, two steps back" pattern that's haunted Lohan's career. As earlier this week, she received a spate of positive press for her stunning Liz Taylor photos
