Singer Chris Brown is dedicating his time to community service for the last six weeks because he wants to complete it as soon as possible. Since Nov 13, Brown has been doing physical labour six hours a day, five days a week to complete his 1,000 hours by the next court hearing in mid-January. There have been a few weeks where work has gotten in the way, but the drill still goes on, reports tmz.com. Brown's community service in the Rihanna assault case requires hard labour, and he's working at a facility approved by the Probation Department, painting, cleaning, trash removal and moving furniture. Last Friday, Brown worked for six hours before he took a flight to Jacksonville where he performed that night at the Memorial Arena. He then flew to Columbia for a Saturday show, then on to Birmingham for a Sunday performance. He took a private jet back here for his community service Monday. Sources say that he hasn't complained or acted up.
