Chris Brown insists allegations he punched a woman at the weekend are "unequivocally untrue".
The Loyal hitmaker was accused of attacking Liziane Gutierrez on Saturday morning in Las Vegas but his representatives have denied the claims and suggested the alleged victim is a liar.
His spokesperson told Rolling Stone: "Making false accusations seems to be a pattern of behavior for Ms. Gutierrez. Whatever her motives, her statements are unequivocally untrue."
The 26-year-old singer is accused of striking Liziane in the victim's right eye using his fist because she had snuck her mobile phone into the private party he was holding in his suite at the Palms Hotel.
