First, Chris Brown broke his silence. Now, Rihanna might be next.

The female pop star's lawyer told reporters Rihanna is likely to appear at a court hearing next month as a possible witness in the assault case against former boyfriend Chris Brown. According to The Associated Press, attorney Donald Etra said prosecutors have indicated to him that Rihanna will receive a subpoena to testify during a preliminary hearing in a Los Angeles County courtroom on June 22.

"The D.A. has advised me that she will be subpoenaed [to testify]," Etra told media gathered outside the courtroom on Thursday (May 28), according to People.com. "She absolutely will comply," Etra said, adding that his client would be subject to cross-examination by Brown's lawyer.

During that hearing next month, the judge will determine if there is enough evidence to move forward with the case against Brown. Brown is facing felony assault charges after allegedly assaulting Rihanna in February. Brown pleaded not guilty to the charges and did not appear in court on Thursday.

On Wednesday, Brown spoke publicly for the first time since the incident, which occurred on the eve of this year's Grammy Awards. In a YouTube video, Brown, appearing with rapper Bow Wow, said into a camera that he "ain't a monster" and thanked his fans for their support. Rihanna has yet to speak publicly since the alleged altercation took place.

Brown's attorney, Mark Geragos, attempted to receive police records and other investigative material from authorities in court this morning. Geragos was seeking to have the case against his client dismissed after photos of a battered Rihanna from the night in question leaked online. The photos were in the possession of the Los Angeles Police Department. The judge, however, denied Geragos' request. According to the AP, the judge told Brown's attorney the motion was premature. Geragos will be able to refile the request after the preliminary hearing.
