Singer Chris Brown has pleaded not guilty to two felony charges after his alleged fight with ex-girlfriend Rihanna in February.

The R&B star showed up at Los Angeles County Court on April 6 with his lawyer Mark Geragos. He stood silent as Geragos quickly discussed the case with the judge, who set a preliminary hearing for April 29, reports said.

Brown was charged with two felonies - assault and making criminal threats.

Outside court, singer Rihanna's attorney, Donald Etra, reiterated promises that his client will do "everything that the law requires her to do. She would be pleased if this was over quickly".
