LOS ANGELES (AP) - Chris Brown's arraignment is postponed until April 6.
The 19-year-old R&B singer, wearing a gray suit, appeared in a Los Angeles courtroom Thursday alongside his attorney.
Brown had been charged hours earlier by Los Angeles County prosecutors with felony assault likely to cause great bodily injury and making criminal threats. He was arrested nearly a month earlier after police said he was involved in an early morning altercation with a woman who identified the "Run It!" singer as her attacker.
Court records list Brown's victim as "Robyn F." Rihanna's real name is Robyn Rihanna Fenty.
The 21-year-old "Umbrella" singer was not present in court Thursday but was represented by an attorney.
If convicted, Brown could be sentenced to probation or nearly five years in prison.
