After six months of flying below the radar, Casey Anthony turned up in a video diary that someone posted online.

In the roughly four-minute clip, recorded in October, Anthony sports a new look -- a blond bob with glasses -- and made no mention of her late daughter Caylee Marie, her high-profile murder trial, where she was hiding out or her parents.

Anthony's defense attorney claimed the video was not released by Anthony and called its posting "unauthorized" and "inappropriate."

Anthony was acquitted in July of murdering her daughter.
