Chris Brown attended his progress report hearing yesterday in Los Angeles Superior Court -- and it was revealed that he tested positive for marijuana in Virginia. According to RadarOnline.com, Los Angeles Judge Patricia Schnegg did not immediately find Chris in violation of his probation, but she has scheduled a November 1st hearing to discuss whether she should do so. Chris has been ordered to report to his probation officer within the next 72 hours.  Chris apparently presented the Virginia probation officials with a California marijuana card, but Judge Schnegg said, "Young people look up to you, you can't be acting like this." Schnegg also ordered the superstar's probation requirements be finished in California, because of ongoing concerns with discrepancies about how much community labor he has actually completed.  Chris is on probation for the 2009 assault of ex girlfriend Rihanna.
