Prior to the February beating that yesterday (Aug. 25) got Chris Brown a sentence of five years probation and six months of community labor, the singer was allegedly involved in two other unreported incidents "related to domestic violence" with his then-girlfriend Rihanna.

According to the Los Angeles Times, a probation officer's report filed with the court yesterday (Aug. 25) alleges the first incident occurred about three months earlier, in Europe, when Brown and Rihanna were in a "verbal dispute." She slapped him and Brown responded by shoving her into a wall, the report claims.

Three weeks before the February incident, Brown and Rihanna were in Barbados, when they had an argument while driving a Range Rover lent to them by a local dealership, according to the report. Brown allegedly got out and broke both the front driver and passenger side windows. No one was injured.

Neither incident was reported to authorities. Brown's attorney, Mark Geragos, declined to comment to the newspaper.

Yesterday, Brown was sentenced to five years' probation and ordered to do 180 days of community labor -- to be directly supervised by the police chief in Richmond, Va. -- Brown's hometown -- as agreed to in his plea deal in June, when he pleaded guilty to felony assault.

A second felony charge, making criminal threats, was dropped at the time of Brown's plea.

In addition to probation and community service, Brown will also go through a 52-week domestic violence program sponsored by Commonwealth Catholic Charities in Virginia.
