Chris Brown Fails Drug Test, Faces Probation Hearing

American music star, Chris Brown tested positive for marijuana use and faces a hearing to determine whether he violated his probation for the 2009 assault on then-girlfriend, singer Rihanna.

The R&B singer was in court Monday for the first time in a year. Los Angeles Superior Court Judge Patricia Schnegg was weighing the impact of his positive drug test and sorting through his community service and travel records to determine whether he has been complying with his five-year probation, according to The Associated Press.

Before he appeared in court, Rihanna sent him a tweet: "I'm praying for you and wishing u the best today!"

Brown responded with, "Thank u so much."
