The case of the People versus Chris Brown continues.

The musician pleaded not guilty in a Los Angeles courtroom Monday to two felony counts - assault and making criminal threats - in the alleged Feb. 8 beating of his girlfriend Rihanna.

Brown, looking solemn, wearing a black sweater, black tie and matching pants, entered the courtroom at 3:30 p.m. followed by his mother, who looked distressed but cracked a smile at a friend in the courtroom.

Asked by Judge Patricia Schnegg for his plea for both charges, Brown answered "not guilty" to each one in a barely audible voice. The judge set the next hearing for April 29.
