Pop superstar Rihanna has postponed a concert in Malaysia this week, organizers said Tuesday, following reports that she accused her longtime boyfriend Chris Brown of assault.
The show will be rescheduled to an unspecified date.

Additionally, the 20-year-old singer (real name: Robyn Rihanna Fenty) is cooperating with police, regarding a domestic violence case investigators are building against Brown, reports the Los Angeles Times.

Police sources told the paper that Rihanna was left with "bruises and a scratch on her face," following an early morning altercation with Brown early Sunday morning (February 8) after leaving a pre-Grammy party. She was later treated at a "major medical facility."

Further details regarding the incident are currently unknown.

Brown, 19, turned himself in to the Los Angeles Police Department later that same day, and was charged with making criminal threats, and remains under investigation for felony charges of domestic violence.

He is free on $50,000 bail.

The couple reportedly got into an argument while driving a rented Lamborghini around Los Angeles' Hancock Park. It escalated, and became violent. Police were called, and Brown fled the scene before they arrived.

Following the incident, makers of Doublemint gum suspended an endorsement deal, where Brown's song appeared in commercials for the gum.

Rihanna's Los Angeles-based representatives informed Malaysia's Pineapple Concerts that the Feb. 13 show would have to be rescheduled to an unspecified date "in light of recent events involving Rihanna," Pineapple Concerts said in a statement to The Associated Press.

Rihanna had been slated to visit Indonesia and Malaysia on her "Good Girl Gone Bad" tour.

Her planned stop in Kuala Lumpur drew publicity after organizers said she would shun skimpy outfits to conform with Muslim-majority Malaysia's strict rules on performers' dress.

The Los Angeles Times, citing law enforcement officials familiar with the case and other sources it did not name, reported that Rihanna told police that Brown had hurt her the night before the Grammy Awards.

A police statement released Sunday said Brown and an unidentified woman began arguing while riding in a car following a pre-Grammy party where they were spotted together Saturday night. The fight escalated when they got out of the car, the report said.

The report indicated the woman was injured, but Brown was booked only on suspicion of making a criminal threat after walking into a police station Sunday night. Authorities said the district attorney could choose to expand the charges.
