Former Growing Pains star Tracey Gold pleaded not guilty Tuesday to charges that she was driving drunk when her SUV overturned, injuring her husband and 7-year-old son. The 35-year-old actress was charged last month with DUI, causing injury while driving with a blood-alcohol level in excess of 0.08 and felony child endangerment. She faces a maximum sentence of five years in prison and a lifetime of Growing Pains reunion movies.
