Brown pleads not guilty in hit-runSinger Chris Brown's lawyer has entered a not-guilty plea for him to a hit-and-run charge that led to his parole being revoked, The Associated Press reports. Brown was charged after a May 12 traffic accident in Southern California in which he is suspected of rear-ending a car stopped at a red light and refusing to give the other driver his license or insurance information. The singer has been on felony probation in the 2009 beating of former girlfriend Rihanna. A judge revoked his probation last week and ordered a hearing. His trial in the hit-and-run case is set for Aug. 15.
