Embattled singer Chris Brown faces another court hearing later this month and Rihanna, the pop songstress he is accused of battering earlier this year, is expected to appear.

Rihanna’s attorney Donald Etra said his client will appear as a possible witness in the assault case against the 20-year-old R&B singer. Etra said prosecutors have told him Rihanna will be subpoenaed to testify, according to Associated Press reports.

The hearing would mark Rihanna’s first court appearance since felony assault and criminal threat charges were filed in March against Brown, and will focus on whether there is enough evidence to continue the case.

If Rihanna testifies, she would be subject to cross-examination by Brown’s attorney, Mark Geragos.

Brown was arrested in February for allegedly hitting and choking Rihanna while the couple argued in a car just hours before they were to appear at the Grammy Awards.

Rihanna, whose birth name is Robyn Rihanna Fenty, is said to have been following the case closely.

Last month, a judge on rejected a motion by Geragos for access to police and investigative records related to the case.

If convicted, Brown faces sentences that ranging from probation to nearly five years in prison.
