Rihanna's lawyer has revealed that his client may testify against Chris Brown in court, following their altercation last month. 

The singer - who refused to speak out against Chris last week in court - may break her silence against the Run It star, if necessary, at his arraignment on April 6.

"[Rihanna] is planning to do everything that the law requires her to do," her lawyer Donald Etra told The Guardian.

"If she is required to testify, she will do so."

Rihanna wants a "quick and expeditious" legal process, Etra said.

He added, "She wants to get back to her life and her career."

Chris has been charged with two felonies for with making criminal threats and faces anywhere from probation to four years and eight months in a state prison, according to the district attorney's spokeswoman Sandi Gibbons.

If Rihanna testifies against Chris it could make his case for a minimal sentence a lot more difficult.
