Chris Brown appears in court a day after Halloween

A day after sharing photos of his Halloween costume online, Chris Brown appeared in a Los Angeles courthouse for a probation hearing.

Brown posted images on Instagram Wednesday of himself posing with friends in costumes reminiscent of Mujahideen fighters, with robes, head scarves and faux beards, guns and ammunition.

On Thursday (Nov 1), he was in court -- dressed appropriately -- for a brief hearing at which the judge said he must return to update her on the progress of his probation after he completes an overseas tour.

Superior Court Judge Patricia Schnegg did not address questions raised at a previous hearing about whether the R&B singer had completed the terms of his community labor sentence.

A prosecutor said a report filed for Thursday's hearing did not add additional details about Brown's service as previously requested by the court.

Brown remains on supervised probation for felony assault for an attack on Rihanna in 2009. He is scheduled to return to court Jan 17.
