Chandler Riggs has officially said goodbye to his role as Carl Grimes on The Walking Dead. The 18-year-old actor was spotted at a Xbox Live Session in Las Vegas on Thursday sporting a short haircut that made us all do a double take. The transformation is a huge departure from the signature locks he's sported on the hit AMC series since 2010. Chandler is set to exit the show when The Walking Dead returns on Feb. 25.
