The extent of the alleged violence against Chris Brown was revealed today as the R 'n' B star faced charges in court.
Brown, wearing a sombre grey suit, was charged with assault likely to cause great bodily injury and making criminal threats at a court in Los Angeles.
It had not previously been confirmed the victim of the alleged assault was Rihanna. But court documents showed the woman in question was Robyn F otherwise known as Umbrella Rihanna, whose full name is Robyn Rihanna Fenton.
He did not enter a plea and only spoke to confirm his name at the hearing, which saw documents leaked to FoxNews.com revealing some of the details of the alleged assault.
The detective's affidavit states that, after Rihanna read out a text from another woman, Brown punched and bit her and deliberately banged her head against the car window.
Brown and Rihanna both pulled out of scheduled performances at the Grammy Awards on the night of Brown's arrest, which occurred after he and the woman in question argued in a parked car in Hancock Park, Los Angeles.
Despite the incident the couple are now reported to be back together. They were seen reunited as a couple at a party hosted by Sean 'P Diddy' Coombs.
