Rihanna and Brown had previous violent incidents

Rihanna and Chris Brown were involved in two domestic violence incidents before his February assault on her.

Court documents filed by a probation officer - ahead of Chris's sentencing for the assault for which he received six months community labour and five years probation for punching, biting and choking Rihanna - state the pair were involved in a furious argument just three weeks earlier.

The pair were in Rihanna's native Barbados, when they began rowing while driving in a Range Rover.

The documents state: "They had an argument inside the car. Brown exited and broke the front driver and passenger side windows of the car. No one was injured during the incident."

Three months before the February 8 altercation, the couple began rowing in Europe, resulting in the 21-year-old Umbrella singer slapping Chris.

The paper states that Chris responded by shoving her into a wall .

Further details of the February incident, which occurred shortly before the Grammy Awards in Chris' rented Lamborghini, have also been revealed.

After Chris allegedly received a text message from an ex-lover, Rihanna said she became "enraged" and slammed both of her fists against the dashboard.

Chris stopped the car and tried to make her leave, with the argument escalating into the assault.

In the report, Chris states he is "remorseful for what I have done".

Neither Rihanna nor Chris Brown s lawyer has commented.
