Hopper Penn…the 24-year-old son of Sean Penn and Robin Wright…was arrested in Nebraska on Wednesday for drug possession. He was actually pulled over for a turn signal violation, with an actress named Uma von Wittkamp in the car.
The cops found pot, shrooms, and four amphetamine pills. As of yesterday, they were both in jail awaiting bail.
Hopper has struggled with drug issues in the past, including a meth addiction.
