Rosie O'Donnell visited Martha Stewart in a West Virgina prison in late 2004/early 2005, as she was always a fan of the media doyenne. On Friday's "Rachel Ray," Rosie talked about her admiration for Stewart and the reasons behind her trip. Complete with an imitation of Stewart's voice, O'Donnell did a hilarious reenactment of the six hours the two spent together that day. Best part? Stewart used mustache bleach for hair highlights in the clink.
