The L.A. County District Attorney denies that Rihanna is no longer cooperating in the Chris Brown case.

D.A. spokesperson Sandi Gibbons tells Usmagazine.com, "We deal with her attorney who says she is a cooperating victim."

After Chris Brown's March 5 court date, Rihanna's attorney Donald Etra said, "I think Rihanna would like this over as quickly as possible. It benefits everybody."

Rihanna, 21, was allegedly assaulted by singer BF Chris Brown, 19, during the early hours of Feb. 8.

With or without the "Disturbia" singer's cooperation, the case will continue on the basis of her detailed statement to police hours after the attack -- and the graphic photos.

Brown is due in court to be arraigned on two felonies April 6.
