I'm with your daughter. I can't even stand the look of her. I started watching BB12 again, and she wasn't nearly as irritating at first. I think being on tv really messed her up. Her voice, her laugh, everything is terrible. I really hope she doesn't act that way in real life. I also can't stand Jordan. She's portrayed differently on the show, compared with how she acts on the live feeds. She's a brat in the house, but the editors make her look sweet.
(Going back to Rachel's voice, in BB12-episode 5, when she tells the others it's time for the Nomination Ceremony, her voice is way more normal. I think the BB13 voice isn't her real voice, it's an act.)
