Pop superstar Rihanna has been identified as the woman who was allegedly battered by teen heart-throb singer Chris Brown. Rihanna has suffered a broken jawbone and contusions to the top of her head, unnamed sources reportedly said.

Brown's ad campaign with Wrigley was suspended Monday until his criminal case is resolved. Brown was released after posting US$50,000 bail. The Los Angeles Times, citing law-enforcement officials familiar with the case and other sources, reported that Rihanna, born Robyn Rihanna Fenty, was the woman who told police that Brown hurt her the night before the Grammy Awards. Both artistes were no-show.

Police said Brown and an unidentified woman began arguing while riding in a car following a pre-Grammy party Saturday.

Several celebrity websites such as TMZ.com, Radaronline.com, Us Weekly and People, citing sources neither named nor characterised, also reported that Rihanna was the woman involved.
