The shocking news of Chris Brown's abrupt Grammy cancelation and arrest in a felony battery case had the industry buzzing Monday about whether his girlfriend Rihanna, also a Grammy no-show, was involved. Police refuse to identify Brown's accuser and no charges have been filed against the 19-year-old singer, who was booked on criminal threats and released on $50,000 bail on Sunday night. "LAPD arrested him, but we have not filed any charges because they have not given us any evidence yet," Los Angeles District Attorney's Office spokeswoman Jane Robison told TVGuide.com. Brown is due in court March 5.
