CHRIS BROWN BOOKED, RELEASED ON BAIL AFTER ASSAULT INCIDENT; HE & RIHANNA PULL OUT OF GRAMMY AWARDS

Both CHRIS BROWN and RIHANNA pulled out of last night's Grammy Awards telecast, following a report of an alleged domestic violence felony battery involving CHRIS on Saturday night. Early last evening, the Los Angeles Police Department said that they were investigating the incident, which took place early Sunday morning.

According to the LAPD, Chris and an unidentified woman were in a car in the Hancock Park neighborhood of L.A. when they started arguing. The argument escalated when Chris and the woman got out of the car. According to police, the woman suffered, quote, "visible injuries" and identified Chris as her attacker. The LAPD received a 911 call, but when they arrived on the scene, Chris had left.

Chris turned himself into the police last night and was booked on charges of "criminal threats." He posted 50 thousand dollars' bail and was released.About an hour before the Grammys began, the Recording Academy issued a statement saying, "We have just been informed that Rihanna will not be attending tonight's 51st Annual GRAMMY Awards. We're sorry she is unable to join us this evening."

A similar statement announcing Chris wouldn't be attending either came an hour and 12 minutes into the telecast. Chris' only Grammy appearance turned out to be an airing of his Doublemint commercial, which aired about 50 minutes into the telecast. Rihanna's Cover Girl ad also aired during the show.

Rihanna was not identified in the police report, but KCAL-TV and the Los Angeles Times, both citing unnamed sources, said that she was the alleged victim. KCAL-TV also reported that Rihanna had bruises on her face and bite marks on her arm. Rihanna's rep later issued a statement saying, "[She] is well. Thank you for concern and support."

As of press time, Chris Brown's representative had not responded to ABC News Radio's request for comment.
