"Virginia Stand Up! A Call to Action" will be held at Virginia Commonwealth University in Richmond on May 15. Proceeds will benefit the Central Virginia Foodbank and the American Red Cross.
Some of the performers lined up for the event include Keri Hilson, T-Pain, Trey Songz, Mario and Ryan Leslie.
The 20-year-old singer was sentenced last year to five years' probation and six months of community labor after pleading guilty to felony assault. He was charged in an attack on his then-girlfriend Rihanna hours before the Grammys in 2009.
