Lawyers for Stephen Belafonte released a statement after the ex-Spice Girl was given a temporary restraining order.
She claims she was the victim of "multiple physical beatings" and that her ex threatened to destroy her career by releasing a sex tape.
Stephen Belafonte's legal team calls the claims "outrageous and unfounded".
They say: "When the degree to which Ms Brown has gone to create a false depiction of her marriage to Mr Belafonte is uncovered, real victims and survivors of domestic violence will be understandably offended, angry and upset."
